I have some thoughts about this. This is not about them having 'detected' commercial usage on your system. This is all about new avenues of monetizing for them and pressuring users into buying into a commercial license. This nonsense started for me a few weeks ago as well, after which I submitted a request online to unblock the account -- which is not being used for commercial puposes whatsoever. Today I received an email stating that they were unable to discern private usage. If they actually capture any of these sessions for commercial usage detection (using some machine learning algorithm) they have some work to do, because some of that usage with my girlfriend has been anything but commercial. The only thing that did change is that I started using OpenVPN to dial into my home network to ensure an encrypted connection from wherever I use my laptop. The changing IP networks is probably what triggering this nonsense. I have no intention on changing that as there are more than enough alternatives to TeamViewer. ps. The mail I received today also had a link to a printed form that is laden with spelling mistakes and duplicate fields. You might want to look into that dear people at TeamViewer GmbH, it comes across amateurish.
