There are niche communities that haven't migrated that I'm okay with using a crappy platform to stay in contact with. That being said I've been using teddit until I need to post.
Teddit is an open source privacy focused read only front-end to public Reddit (like Nitter for Twitter) that ensures your browser never gives them a hit. Its styled like old.reddit and there an alternate called Libreddit that follows the new style. They directly hit Reddit instead of the API so they aren't affected by the recent drama. You can also self host them if you want even more protection.
