I'm not centrist, but I think I can give a reasonably fair account. I was among the first to organize against Flock (YC S17).
Flock was accepted into YCombinator's Spring 2017 batch. Prior to YC, Flock CEO Garrett Langley had had a couple of fair-to-middling business successes and was looking for his next opportunity, which included better toilets. The story goes that he got the idea for Flock after a local police interaction where he happened to have helpful video footage. [1]
Flock quietly expanded into HOAs and neighborhood associations [2], and by 2020 had begun developing partnerships with police departments across the country and fusion centers [1], which are regional clearinghouses of data from multiple sources assembled together for law enforcement purposes.
By 2025, Flock had managed to grow to 80,000 cameras operational across the country. In June of that year, 404 Media, an independent journalistic outfit comprised in part from former Vice journalists, broke a story about Flock being used in the investigation of a woman who had self-administered an abortion in the state of Texas [3]. Flock quickly released a statement trying to "clarify" the situation, but everyone involved was lying through their teeth [4].
Up to this point, Flock had spread across the country in a pretty clever way: they built direct partnerships with police departments through sites and resources they commonly used, like https://www.police1.com/, and by hiring former police officers for sales positions. Police departments were coached to consider Flock an "ALPR" (which it very arguably isn't), which would make it not "new" technology under most local police technology procurement processes, which meant that police departments could purchase it without city council or other local agency review. To make the purchases, Flock helped to connect police departments with public money in the form of grants. For example, funds might be available for programs meant to reduce "organized retail theft", and Flock would say, "well, we qualify!", and then police departments would not use the systems to investigate organized retail theft. [5]
Throughout the Summer of 2025, people started asking questions about these weird cameras popping up everywhere, and 404 Media managed to produce one widely-shared article after another about Flock [6]. Other media outfits started to pick it up, and stories getting national attention included law enforcement officers using Flock to stalk former romantic partners or love interests or anyone else they wanted to (because Flock was built without any controls in place to prevent that kind of abuse; Langley himself repeatedly said it wasn't their job to do); Flock sharing direct access to data with federal agencies; Flock lying about the direct access that federal agencies had; then federal agencies using Flock's data-sharing capabilities to easily get around the really thin limitations that were put on that after reporting about it; Flock being used to surveil protestors; and on and on and on.
Essentially, Flock became a textbook case study for every single abuse of state surveillance power you can imagine.
Garrett Langley attempted to navigate all of this by absolving Flock of any responsibility, denying any wrongdoing, outright lying in some cases, and referring to people running crowd-sourced maps of Flock installations as "terrorists" -- which, many months later, he would get around to walking back. A little bit.
Some groups were able to legally acquire some devices and found that they had really, really poor security generally, and also that they had capabilities that weren't being advertised to the public. The prime example of this is that Flock would coach police departments to tell the public that Flock was "just an ALPR" and "only captured pictures of license plates", but meanwhile the software on the devices was written to capture images of people and bicycles and cats and dogs. On the one hand, the public would be told that the system could only track vehicles; on the other, Flock's own marketing materials advertised the ability to find pedestrians by a description of their clothing, and police departments were being trained on how to use the system to follow bicyclists. In another case, Flock representatives would say the system didn't have a "heat map" capability (showing a density of hits for a particular license plate in a particular area over time), and then it would turn out that not only did they have that capability, but internal trainings with law enforcement departments were explicitly describing how to use the system to predict where a particular person might be at a particular day and time (called a "pattern of life" search).
In 2026, public opposition to Flock has become a national conversation, and states like Oregon have started developing more restrictive legislation around the use of it and similar technology.
Flock wasn't the first ALPR company. The technology has in fact been around for a while and there are other established players in the space. However, Flock quickly had all of the hallmarks of "surveillance capitalism" -- an effort by investors like YCombinator, Founders Fund, Andreesen Horowitz, and others, to build out a national realtime surveillance network of everyone's movements and then monetize it, most obviously by providing access to an increasingly authoritarian federal administration. Americans, surprisingly, have found the will and energy to organize against this in large numbers that cross the typical political divisions.
