Or how about instead of passing the cost off to users, Steam actually supports them from their own profits? After all, they are profiting from free work.
We can't be pushovers about this.
Such donations might even be tax-deductible revenue for Valve, so even the finance bros should love it.
Although I would prefer if Valve simply commits to a fixed percentage of its Steam fee to be donated...

And by all means, if a game community is so toxic that it has to be policed by extreme measures, it is perhaps indeed better to avoid playing such a game altogether.
Space Marine 2 was the latest one for me, but Steam is great at refunds if you do it quickly enough.
For me it crashed after the first click in the menu.
It actually gives a far better user experience for games like Battlefield 6, because on Linux they just don't work at all. Try it for yourself - it won't even start!
By contrast if you run Battlefield 6 on Windows, eventually you'll end up playing it, and you'll wish you hadn't. It's a shitty buggy mess and you'll hate it.
So, notch up another score for Linux!
