I used TeamViewer to let a friend view my screen while we worked on a hobby project - entirely non-commercial. TeamViewer slapped the 'suspected commercial use' message on us. We filled out the form and emailed it to them as instructed, never heard a peep. This was pre-coronavirus.
I tried contacting their sales and they claimed they don't provide support for the 'free' version. Well if there's no support and they're happy to lock it down to prevent it being used with NO recourse then what do they expect when people leave? I setup WireGuard and used Remote Desktop instead. Good riddance to those clowns.
Totally understand their need to make money, but why not offer a paid personal edition instead of making people suffer for a free version like that? How does it do their business reputation any good?
