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.
Their 7 (?) years of software support is kind of misleading to me because they stop getting chip-level security updates after something like 3-4 years due to the specific Qualcomm chip they use. Not to mention the chip is on the slower side of today's phones, let alone phones 7 years from now.
I can see how others might be fine with that though, just my 2 cents.
