YouTube getting rid of dislikes, adding in music mixes, and of course striking videos while providing less than adequate descriptions (if any) of the offending material.
Gmail mixes in ads with your emails more aggressively than ever before.
Google music has been replaced with YouTube music, an inferior, less usable version of the same product, but now it's tied in with your YouTube account so you get spammed with music recommendations that are frankly terrible.
Google Drive, actually scanning your files for unapproved materials.
Google Mini with a voice so eardrum-burstingly loud (and shrill) and no ability to control it separately like you can with Maps.
And of course their search itself has experienced a very noticeable drop in quality and seems now to be a Google Marketplace of Approved Agendas. Not just with the pop up "helpful" cards, but with the actual search itself. It's quite eye opening to do the same search on DDG and find useful results that weren't visible on the first 10 pages of Google.
This isn't even including the other products which I did like, but Google suddenly decided that I don't need anymore.
Google Docs still works well though.
