How is this forum so bad?

I can't search anything, I can't see my old posts, I can't find a solution that was posted to one of my questions. 

The old forum system was much better. Why would you ever downgrade in this manner?

You can see your old posts in your profile: https://my.tek.com/public/d6bbeab5-5256-ee11-be6f-00224802d199/forum-posts

The old forum is still up: https://forum.tek.com/

There's also several unofficial community groups going by the name of "TekScopes" or something similar.
