Something I noticed the other week - Chrome on Windows will scan my desktop on startup (all the icons go back their generic version, and then return). Why would they do that? My desktop isn't where the cache is.
If any other company did those sorts of things in persisting pieces of their software all over the OS without easy removal for non-technical users, people would be calling it malware or spyware.
I would think it just uninstalls. Are you claiming otherwise? I'd love to try and reproduce what your claims are (fact check).
