Earlier quoted context omitted.
I almost hesitate to share these because I too found that Reddit's dark patterns were a large part of what helped me break that habit. I recently discovered teddit.net which is a frontend for reddit with all dark patterns removed. There is also an alternative front end for twitter called nitter.net that you can use the same way to avoid the app / login.
For reddit, IMO the simplest things you can do to improve the experience is to force the old reddit design (old.reddit.com) when on desktop, and use any app except the official app when on mobile.
Something that irritated me, for instance, was how they decided to remove the account activity panel, making revisiting recent links waaay harder. That coupled with the fact that they also remove a link from the front page too quickly is also making me to use the site less. So much for the dark patterns, heh.
