Makes me sad. Some of those 32-bit apps are awesome. I do love that you can click to go to each company's website, can show in finder (of course), and that it found things in the System Application Support folder. The Last Used column is helpful. I guess I shouldn't be too sad because I haven't run many in a few years.
I like this too - shows a yield sign for - "It may or may not run correctly on macOS 10.15, depending on how the app handles situations where its 32-bit components would normally be used. Check for a more recent version or contact the application's developer for more information."
This company has been around forever. I trust them.
I do recommend adding an app that cleans out all the related software (just be careful) when you delete the app (you can in the app).
