The issue is treating all third party stores as side loading, when no other category of device does this. It violates EU anti trust laws, and possibly US antitrust laws as this lawsuit explores. We trust people to have figured this out for PCs and macs, mobile is quite literally no different at this point.
I'm very happy my 12y old kid can't just sideload shit nilly willy. He legit Googles minecraft hacks and downloads random apks and stuff if he gets the chance)
(his phone is also fully locked down with parental because a 12y old should have free reign on the internet, but that's beside the point)
honestly i think letting kids experiment on their own devices and get them full of malware is a good thing. its the perfect time to learn since a kid doesnt have any money to steal anyway, and the parent can just come in and factory reset the device if needed. Too much protecton means people never learn how to be responsible without it.
Oh yeah, I don't have an issue with them ruining their devices. I just have them locked down because I don't want them to have free use on the internet. So much mindrot on there...
what if I have a store that checks security properly? I mean how do you believe app store and play store then? belive them simply because they are corporate overlords? this is like saying "we don't deserve freedom because we may do crimes"
