I don't quite understand the need for nitter. I don't use X/Twitter due to what it accesses, not due to the front end.
Not being able to access it might change that.
Are you talking about WeChat, or truth social? I didn’t know nitter worked on either
If you're happy getting your information second-hand, I guess that's your choice, but not everyone is. If I read a news article that cites a tweet as a source, I'd like to see the rest of the tweet thread for context. It might not be what it seems.
