It’s probably because TLS uses your system clock to validate certificates. If your clock doesn’t match the server you’re connecting to, TLS fails and you get an “https failed/connection is insecure” error. And Windows likely uses https in the store to ensure MITM attacks can’t replace valid downloads with malicious ones.

Microsoft: “Let’s fire our QA teams. We’ll force our dev team to use AI in coding. Then we’ll have the public test it.”

Yeah, mods on proton get weird sometimes, especially if they require things like Microsoft Visual C++ Redistributable packages/runtimes. I think ProtonTricks allows you to install those directly in the prefix, but I personally haven’t had any success with that. Every time I try something that involves stuff like that, I end up getting white screens, black screens, or just full CTDs.

Yeah, the sad reality is that there are some critical pieces of software that just outright refuse to support other OSes. Personally, I’m forced to use Macs at work because QLab is the industry standard for my line of work, and that software is only available on Mac.

You can play WoW on Linux, though there may be a few extra hoops to jump through when installing the BattleNet client. Hell, there was even a test case where someone got it running on their SteamDeck as a proof of concept.

It runs in Wine or Lutris, which acts as a compatibility layer. The compatibility layer doesn’t emulate Windows directly. It just translates the Windows-specific stuff into something that Linux can use, and vice-versa. That’s why lots of games can actually run better on Linux, because you’re running a Windows native program without fully emulating Windows. So you don’t have all of the Windows bloat that tends to bog down gaming PCs.
