1. I didn’t realize what community it was because they weren’t specific at all. They just asked for an alternative.
2. You don’t seem to realize that it is literally true: everyone gets compromised. I mean not only companies but it also applies to self hosted systems. One example was that my home server got hacked a few years ago. Magically virus filled executables showed up in thousands of my directories. This was a Linux server. Any open port will get hijacked if it is open for long enough.
3. This type of product asked about literally does not and cannot exist in a self hosted situation. The only way they can work is if a critical mass of other users are near the device, also using the supporting app, with Bluetooth enabled, that way you have any chance of its location being reported.
4. The data breach that happened in this case affected data that almost every citizen has out there anyhow from a dozen other data breaches. Yes it obviously is sometimes due to irresponsible practices but there isn’t much to be done about it now that the data has been out there for a decade.

I know you mean well here but you’re off base and it’s coming across as lecturing me about something you aren’t fully informed about. I am not saying people shouldn’t care about privacy. I’m saying if you want this type of product, all the concerns you’re mentioning here are literally impossible to avoid. The best you could do is find the company with the least number of breaches and then pray they remain that way. But that doesn’t really get you very far.
