Fair point. But at least, on Telegram, you have to actively seek out such channels to join and they don't otherwise impinge on your use of the service. It's not like other social media outlets where there's a central site which endlessly shoves crap you don't want to see in your face, every time you visit.
And yes, I know that, strictly speaking 'Telegram != social media'. But, with Telegram Channels, it does kind of cross over into the 'Discordy' end of social media.
