Why not?

1. By buying a Pixel phone and degoogling it, you are rewarding good behaviour and punishing bad behaviour, corporations need to be trained like dogs.
2. Google is not going anywhere and their primary objective is profit. By buying a Pixel you are signaling to them a viable revenue stream that doesn’t violate people’s privacy.
3. You don’t even need to give money to google directly, you can buy a second hand-one.

I say, vote with your wallet.

Can you post a source about either of those claims? I’ve found nothing to support either of them.

Telegram does have E2EE chats (called Secret Chats), though they are only one-on-one, not enabled by default and their encryption is dubious.

Allegedly the former. By “allegedly”, I mean that Telegram is definitely uncooperative in moderation of illegal content, the alleged part is that that is the motivation behind the arrest. I also read somewhere that he was accused of tapping into Macron’s manager’s communications, but I can’t find the article and I don’t know how reliable that statement is.
