Most of them jump out as immediately dodgy -- except Stylsh. That is the only one I've ever used on the list but it's been several years.
"zoom", "LibreOffice Editor", "Enhanced Image Viewer", "Video Downloader PLUS"
I guess I shouldnt be surprised on how many use "LibreOffice" or other legit company names to lend legitimacy to themselves. I'm wondering if companies like Zoom don't audit the extension store for copyright claims
I for sure used to use Video Downloader PLUS when I still used chrome (and before youtube-dl)
Stylish was sold in 2016, and has had spyware from at least 2018 on.
HN story about what Stylish was up to 7 and a bit years ago:

I'd assumed most people would have jumped ship to Stylus [1] after that, but most people probably never heard anything about what Stylish was/is doing.
