I'm with the above commenter, I used the old reddit on mobile for a decade+ and always enjoyed it. Also, there used to be i.reddit.com which was great for mobile - but it looks like they've gotten rid of that.
I've stopped using Reddit now. I liked the freedom of speech and the curiosity of the users. Freedom of speech had been eliminated totally. Curuisity can presumably be found in some niche subreddits - but even the niche subreddits I used to frequent have fallen.
