Alternative to Microsoft/Mac operating systems.

I am a Linux desktop specialist for the last 20 years and it has become apparent to me that many of you are being held hostage on your computers by your choice of operating systems. With all that is going on now, it would be a refreshing change to see people stop supporting the likes of Bill Gates and others that use exploitation as their methods of operation. If you want a free demonstration of how easy it is to switch I would be pleased to show you.
