It's got a platinum rating on ProtonDB. It looks like the native versions aren't being supported anymore, but they still work. I don't blame them. The game has gotten a lot smaller over the years and I'm certain there's very few Linux players on it. Regardless, the Windows application seems to work perfectly fine for Linux users. Yeah, native is ideal but it costs extra money to maintain two (or three) versions.

Anyway, you can't say they're sabotaging Linux support when they also purchased EAC and had them add Linux support. They may not be perfect with Linux, but they aren't sabotaging it.

Edit: Why is this being downvoted? If you want to downvote you should be able to articulate why. What is the expectation for them to do? The game has clearly been on the decline for a while, and I'm sure they've got the numbers for their player counts by system. They have limited money and need to support the game still. Why would they waste it on supporting a native Linux version if it isn't being played and the windows version works perfectly on Linux? If they didn't want Linux to exist, why would they make EAC work on Linux? Explain how you think they're actively trying to harm Linux (sabotage) instead of merely maybe hurting it as a side effect passively.
