Yep, especially for young people in the United States.
People have become so attached to “one place only for everything” that something as simple as blue/green bubbles (and associated service differences) will be enough to isolate.
The messiah of maximal convenience makes differentiation harder and harder for everyone.
(And for everyone who says “Everyone here just uses Telegram/Whatsapp/QQ/Line, not a problem over here!”, guess what, you’re still probably gonna be exclusionary to other services just like the blue/green folks. It just doesn’t happen to affect you.)
You can use the Web Archive, if those posts are saved, you’ll see it without ever touching a reddit server. You can’t comment or give awards or anything, but you’re not locked out completely.
Or you can use a 3rd party app. The team behind Youtube Revanced have patched most of the major (Android) ones to still function afterwards. https://web.archive.org/web/20230705025421/https://www.reddit.com/r/AfterVanced/comments/14m3wgo/reddit_apps_for_which_patches_andor_patched/
