Companies know this but they don't care because there are rarely any consequences that cannot easily be mitigated with cheap PR tactics. Even now you are responding to a PR statement that is trying to reframe the issue as users simply not understanding what Mozilla is doing when in reality Mozilla knows full well that this goes agains the explicit wishes of a large part of their userbase but have chosen to enable this anyway. This isn't a communitcation issue. This is a fundamental "who does Mozilla serve" issue.
