Only on Windows (and only after the game had already lost around 80% of its player base), which makes it effectively useless. Because they have a Linux build, there is no way to prevent cheating at a larger scale.

It's fair to argue I have no evidence of the cause of decline. I cite my frequent interactions with hundreds of players in the community, and streamers like Burnt Peanut. However this is qualitative, not quantitative. Me and my friends stopped playing because of the cheating, and so did every other one of my friends who picked it up. It wasn't that we wanted to stop playing the game. It was the cheating.
