I was working on something adjacent to this for a little while.

It was a Chrome extension which allowed a user to upload a list (pluggable community-maintained lists, akin to ublock). It would light up when a user was on a site in the list with details about the site, the ownership/board, recent news, etc.

It also had a space for recommended alternatives. I built it because I was tired of giving money to companies who used the profits to make society worse.

I’d be down to pick up work on it again and get development going in the open or shift to work on the more commercial oriented design you describe. Lmk a good way to reach you if you’re open to it.

If you’d rather I can set up an email for this alias I just don’t have one handy to post publicly at the time of writing.
