You underestimated how terrible things will become when a phone number is recorded by a stranger. Here, if a phone number is leaked, it will be used for searching for all possible data of that owner, and phone calls from loan companies or even scams will be endless.
Where is that? The US? I feel for you guys!

How FB Messenger deals with multiple accounts is really terrible, as the user has to log out A first and then log in B. Moreover, I am not sure about if FB Messenger with Signal Protocol is more secure now, but some people were banned due to sending adult pictures before. The UX details in desktop clients also annoy me.
Yeah, it's not perfect. But it is the most convenient for me for my typical every day usage.
 
There is a myriad of reasons why you don't want a stranger to get hold your personal phone number. People whose job is fairly high stake understand. It also makes targeted SIM-swapping that much easier for potential fraudsters.
Not a problem I have to deal with.

I'm sorry to inform you that ad blockers don't really protect your personal information or messages from being read by attackers. I'm surprised someone who seems to be well-versed in cryptography doesn't know this.
I don't put anything personal in my messages that would actual leave me open to an attack. If I'm doing that, I use PGP.

Facebook Messenger is extremely slow when it comes to search. Try doing a keyword search in Facebook Messenger, e.g., to find the travel plan you and your buddy talked about three months ago, it just can't do it like a 21st century messaging app should.
True, it's not the best.

I don't really understand the point you're trying to make with your reply. I like Telegram. You like Facebook Messenger. To each his own. Nothing is truly private. That goes without saying. It's all a matter of degree. Old hash algorithms get deprecated as computing power explodes and quantum computers will surely usher in a new era.
When algorithms can hack PGP, then nothing that exists today will protect your privacy. What's your point?

My point is privacy is relative. You go for the messaging app that's MORE protective of your privacy. And in this case, Telegram is more secure than Facebook Messenger.
