@x0rz The arguments aren't wrong, but I disagree with the conclusion.
Some of the things are unnecessary (Phone number link), others (cloud storage, contact "theft") are integral to a good messaging experience.
I'm a proud Telegram user. While I'm also starting to explore alternatives again, I'd much rather have everyone use it than WhatsApp.
Imo it's by far the best compromise for now that's ready for the masses.
