So some thing happned that made me alot more woke on my privacy.
First of all: seems my HTPC looked to be compromised somehow (was apparently a UI glitch, logbooks didn't gave anything, all virus scanners said nothing detected, reboot fixed it somehow)
then a day later (today) i was talking about a new subject to me, with my phone in standby on the table, with when i opened it up, and went on a video sefrvice, i saw ads, but 90% of all ads were relevant to the subject, which i never looked for on the internet before, so apparently my voice was analyzed for sure.
Only services running were "anonymous usage stats" & "google play services" thanks to battery management active.
These events made me do several things:
1) stop using my smartphone (old nokia FTW)
2) make one of my pc's disconnected from the internet
3) start to do proper secure back up management
4) for services: use only SMS 2FA.
Very weird and scary times for privacy..
