1. I think targeting compatibility is 99% as good as targeting native.

2. You’re discarding the shifting software landscape. Steam OS and Linux are trending towards higher PC gaming market share. macOS has proven you don’t need much market share to force widespread (but not universal) compatibility.

3. I don’t see the value in a purist attitude around Linux gaming. The whole point of video games is entertainment. I’m much less concerned with if my video game is directly calling open source libraries then if my {serious software} is directly calling open source libraries.

On point 3, I guess my views are different because my {serious software} is usually work, and if it stops working that's kind of a B2B problem and part of doing enterprise. It's just business as they say.

Gaming is much more meaningful to me as a form of story and experience, and it is important to me that games keep working and stay as open and fair as possible. In the same way it is important I can continue to read books, listen to music or watch movies I care about.
