If they’re not using it, why does it matter what happens to the license? There’s a “it’s the principle of the thing” argument sure, but practically speaking this is irrelevant. Shitty company does shitty thing that should have no practical impact on anyone because nobody should be using their product. What exactly would change for people not using TeamViewer if they hadn’t revoked those licences? The argument is that anyone still using TeamViewer deserves this, and anyone who isn’t isn’t actually impacted by this change so it’s irrelevant.
