I was able to clone my apartment fob using a tool I got for $30 on Amazon, and it even came with extra blank fobs and cards to clone to. Flipper Zero can more than just clone RFID keys, but my point is that the tools exist to do all the things it does and do them cheaper, and they're just as easy to use.
If you really need a tool that can do them all, though, I can't really argue with the utility; but I do kind of agree with the GP comment that Flipper didn't exactly do anything that hasn't been done before.
And that's really it. It's purely a marketing play. I guess my other frustration is when I see people who I thought were pretty clever not realize that
No offense, but that is a pretty one-dimensional view of products and businesses. So many great products are just an exciting and/or user-friendly version of a simple concept and well marketed which opens up the doors to a much larger audience than the original concept otherwise would've received.
This approach isn't a cheap cop out, it is serving a genuine utility and bridging the technology to more people.
