The subject of this discussion is non-technical consumers selecting default options, getting their phone OS automatically updated and then wondering why their phone is a bit slower. They're not making an informed choice about upgrading their OS, and are getting an unexpected behaviour they're not happy about. This generally doesn't happen on Android because automatic major OS updates don't generally happen. You upgraded your phone yourself and you know what you're doing, so if you had a problem with performance or otherwise you've got no recourse against the carrier or phone manufacturer.
