Seems like OP has a big grudge towards the project and not the Telegram as a whole. But please be cautious as it could affect the reputation of this decentralized messaging app. Telegram allow us to freely community in our own rules, perhaps, you have been banned because of spamming or maybe other users reported you for some reasons. It is not the Telegram's fault but with the people who reported you or the rules you didn't obey.
For me, telegram was the best messaging app which is really suitable in the world of cryptocurrency. It just adhere to the characteristics of crypto.
Well, whether if this is just a personal issue, we all know that telegram channel really does a lot of scammers and false information. This may be considered as trash because of that, no one filters it and no one can prevent the scammers from doing anything they want.
I don't agree, telegram was only considered as the best because no one can compete with how it is easy to communicate through it, but because of that, it becomes the place for most scammers.
