#2I still don't think I've seen an actually useful application for a Flipper Zero. It's all just "use this to change store price tags" or "here's how to disconnect all bluetooth devices", but also "don't actually use this, because it would be illegal, this is just for educational purposes"

#3I am overjoyed to see this story here, we haven't gotten a lot of these hacks lately. Well done!

It's useful for dealing with the industrial equivalent of IOT garbage

This one provides the source and asks you to build it yourself so at least it has some credibility for the "education use only" claim.
I've seen similar things posted on here before that had a binary build only and zero technical documentation. It was really hard to see any kind of research or education value in those.

Turns out it's what they said it was all along, an educational device.

Beside of how the media often tries to present it, the value of Flipper Zero is not for everyone to "become a hacker with this simple app".
Its value is to provide a standardized hardware platform for (white hat) hackers for probing, prototyping, refining and sharing of security research in the fields its hardware supports (Sub-GHz RF, NFC, IR, and custom external boards via simple Input/Output pins).
Prior to that, everyone who wanted to research e.g. RF security had to either build/assemble something custom or buy much more expensive equipment. This created a barrier to collaborate on research, as everyone had to buy/build the same setup.
On top of that, Person A researching some RF topic selected an RF-transceiver from Company X, Person B used a component and a proprietary SDK of Company Y, so consolidating both work streams for a better foundation for all RF-related research required alot of time and effort from someone, breaking workflows of at least one group of researchers, etc.
In contrast, security research which utilizes Flipper Zero can be reproduced and built upon by everyone. All the work is harmonized on the same Hardware architecture, so it's easy for someone familiar with the platform to dive straight into a new idea without having to build a new breadboard, select a chipset, buy additional probing equipment etc.

#8This is pretty dangerous. At least in my country the displayed price must be honored and they cannot refuse the sale.

I use mine for all sorts. I volunteer at a second-hand shop so use it to set up remotes for donated media devices, I've used it to run scripts to apply the same changes to many computers that aren't on a group policy via BadUSB, I've used it for toys-to-life games, and very much more. There are plenty of genuine uses if you're cluey.

Usually the advertised price must be honored, because it may have brought the customer to your store.
For prices displayed on the shelf-label inside the store the law is usually not that strict (YMMV), as a shop-owner can refuse sale on check-out (otherwise I could put a pricetag on e.g. a shopping-basket and the shop-owner would be legally required to sell me the basket...).
Besides, most shops I've seen (in Europe) already moved from Infrared communication to RF (NFC or proprietary), for centralized shelf-label management without handheld devices. So all this study (and the underlying reverse engineering of the IR-protocol) might do is probably accelerate the transition from IR to RF-based ESL...
