The Chrome team says they’re not going to pursue Web Integrity but…
it is piloting a new Android WebView Media Integrity API that’s “narrowly scoped, and only targets WebViews embedded in apps.”
They say its because the team “heard your feedback.” I’m sure that’s true, and I can wildly speculate that all the current anti-trust attention was a factor too.
Proton is made by Steam, which locks you into their platform.
However Wine in general, as well as Lutris also keeps getting better which is great.
Proton can also be used by other tools like Bottles. It’s very similar to Lutris but with a more general purpose focus, rather than just gaming.
