I dropped Teamviewer after they sent threatening emails claiming I violated their EULA. I got emails falsely claiming I was using it for commercial use, when I hadn't logged in for months. Ended up switching to Anydesk, which doesn't require an account to set up (meaning they can't spy on me or "analyse my use" as per the email below)
