So Teamviewer still claims that they only depend on whether you've selected "commercial use" or "personal and commercial use" upon installation, as well as using windows server. Not sure that I trust that, but they do have a process to remove that free commercial trial expiration:

However it sounds like they've completely dropped all support for free usage (no phone, email, or forum support), have changed their software to lock people out, and this form indicates that it "could" take up to 30days for a response. The form requires a log file of your teamviewer usage.
It's been years since I've used it, but I think I'd shy away from Teamviewer from now on. There are other solutions, and while few are as easy as teamviewer, they are clearly tightening the noose and forcing more people down the paid path.
My guess is that eventually, their servers will stop accepting connections from older versions, so even those who don't upgrade or choose to install previous versions will eventually become locked out.
