Android and said manufacturers purposefully do everything in their power to make this as awful as possible.

For example, you can't relock the bootloader on any device except pixels. Why? No reason. Just fuck you, I guess.

That's a huge security hole that they're creating, intentionally.

What's going on is they are hoping that if you do use other software that you get malware or get scammed. They are literally, actually, undermining their own device's security just to send a message.

These people are psychotic.
