Slack and Discord are better in this regard how?
Discord and telegram have premium but discord is way more used and have streaming features (really costly) and telegram premium is not that widespread and no one but power users need it
And the numbers seems to be more 200/700
Telegram doesnt even have that.
Its based in UAE, with a mere legal presence in Germany, their official explanation is that durov is financing it sincd its beginning in 2014, how? From his VK money.
This could've been believable, if telegram worked like WhatsApp with Minimum storage requirements, but its totally the opposite with huge hosting xosts and no clear funing source.
