A lot of important information is on Twitter. Being able to access it without giving them your personal information and without jumping through hoops is a good thing.
Not being able to access it might change that.
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.
Are you talking about WeChat, or truth social? I didn’t know nitter worked on either
