I don't know how many people have this practice, but Reddit also has become a good "answers" and "research" site to help find people what they want through Google Search. For example: If I search with "Alexa vs Google Home reddit", I am likely to find a lot of useful information from mostly real humans and their feedback openly available on the very site called Reddit. Omitting that "reddit" part in the query will lead me to the other news sites and blogs run by journalists and spammy media companies contain a lot of bullshit that I chose to only rely on Reddit for my quest for information.
I wonder why Reddit would want to charge consumers of its API, without providing any premium services like let's say, Twilio etc. Reddit must focus on monetizing its content and more strategization that will bring in more ad-revenue or user-generated monetary value rather than going after 3rd party API consumers that ended up doing a much better job of building a simple front end app for their content.
