What alternatives to TeamViewer are people using?

I have been hit by their sudden "Commercial use suspected" even though I
only ever connect to one 86-year old friend. He and his wife have 3
Windows machines and he has just bought 2 old iMacs, and is trying to
move to Mac in spite of my protestations. Hence a flurry of connections.

Teamviewer has a form to fill in to protest private use, but here it
just leads to an error page. I found their forum, but all that reveals
is a huge thread full of similar complaints, so it looks as though the
Teamviewer free option is on the way out. They seem to be manually
deleting any references to rivals on the forum and also any email
addresses.

I still help a couple of commercial companies with their IT, but always
in person. I used to recommend TeamViewer, but having delved into the
shambles that is their web site, I now think the time has come to find
an alternative that works to access Windows and Macs.

Any suggestions gratefully received.

I use ScreenConnect - my favourite remote control. Don't think there is a free version, though.

Have also used Splashtop - works, nothing special. Again, don't know if there is a free version.

Agree with VPN and RDP if feasible.
