Code is open source and it's been scrutinised.
Not so much the code I find suspicious, but the number of Tech Youtubers that have suddenly decided to start promoting it as a Windows alternative.
Normally whenever something happens to drive a call to make the switch, they focus on Mint, or some SteamOS derivative.
This time around, it is all ZorinOS. I just found that odd.
Probably because its UI has several themes that are polished and give the look and feel of Operating Systems people are familiar with. It might help doing a smooth transition.
Most people only use a computer to play games, browse the web or type documents. The OS doesn't matter to them as long as it doesn't interfere and prevent them from doing what they want and doesn't spy on them.
