I saw this in a YouTube video about some indie video game. They had a native linux port. The userbase was like 99% windows and 1% linux, but 99% of the crash reports were from linux users.
This and the "problems" with adding anti cheat software that works with linux is just too much for most to bother.
Might be because the average Linux user is way more aware of how useful a crash report can be and therefore actually submitted them.
At least most Linux users I know actually read error/ crash messages and not just call someone saying there was some pop-up, I just clicked ok and the game was gone.
It does. I am disappointed in the game studios who refuse to allow Linux players, though, such as Bungie. I'm certain that Destiny would be playable if not for their obstinacy.
