Site devs need to see the threat from browser engine monopolies too. Valve literally started pouring resources into Linux gaming just because Microsoft looked like they were trying to dominate game stores on Windows. Chromium actually dominates the web. I guess at least base chromium is open source. Still though, one of those markets is way bigger than the other and it definitely isn't Linux gaming. (God I love Proton/WINE and how far we've come!)
