I feel like I am feeding a troll, but let me break this down:

If you have a gun, you can point it at anything and pull the trigger, you don’t need the permission of the manufacturer to do so.

Not with a phone, you CAN’T load any software you want into your phone.

That’s the difference, you can do whatever you want with a gun, and if you mess up, you go to jail. You can’t do whatever you want with your phone, only what the corp.s (apple) allow you to.

*if google /OEMs still provide drivers for AOSP (check calyxos blog, google stopped doing it and it is killing custom ROMS)
