I don't care if anyone has a Xiaomi, Oneplus, Samsung, etc. Each brand is using a modified version of Android, and they chose to be compatible with each other. But for example the "blue vs green bubble" drama is a thing specifically because of Apple locking their unsuspecting users into a closed ecosystem. And it sure isn't Android's fault for not being compatible with it.
The more power a company like this gains, the worse will it be for the whole industry.
Virtually any company big enough to make a worthwhile phone is going to do terrible things. Think a given company is an exception? They won’t be once they get larger.
That being said, the fact that “everybody does it” doesn’t make it okay. The “blue vs green bubble” shit is nonsense that’s totally unnecessary.
