My opinion:
1.) Bridgy Fed (https://fed.brid.gy) is good for the fediverse.
2.) Threads (https://www.threads.com) is good for the fediverse.
3.) If you disagree with #1 or #2, the good thing is that you can block either on a user-level. You don't need to hammer folks like @… for also being @….
4.) If someone is hurting your experience, you can block or report them. You can also create keyword filters to block haters. This is supposed to be enjoyable.
