When Reddit started doing this it effectively broke my redditing habit. I know these things are annoying but for anyone who is trying to use social media less... Twitter, Reddit, and Instagram are almost unusable without their apps. They are basically useless if you dont sign in on the browser on your phone. It's great if you want to get off them.
Reddit seems perfectly usable as an unauthenticated user. I know they present a more spammy version to users landing from google, but nothing is blocked behind more than a click or two. I think that's just good business sense because you want to monetize your firehose of less engaged users and coddle the ones that are more engaged and producing content.
On desktop. The main mobile version blocks essential features, like browsing subreddits or viewing all comments on a post.
(Alternatives like old.reddit, i.reddit and teddit aren't completely broken but aren't great on mobile either)
