I've been trying various Linux flavours every year for 10 years or so. The last year I tried Arch, then EndeavourOS, which has been my most successful Linux exploration I've ever had, and given me huge hope. However, there are still a few things preventing me switching it to my default OS.
I'll put aside Games that need Anti Cheat, as I doubt that will ever be fully fixed, unless Governments force game devs to support more than just Windows.
Here is what doesn't work for me:
- Streaming services like NowTV. (Works in Windows in browser only)
- DRM proected VST's for use with Reaper (not via Wine)
- Roblox (Using Waydroid was not very successful)
- Office 365 (I like Libreoffice and OnlyOffice but fact is Word and Excel are just required for some stuff)
NowTV is to watch the formula 1 race live.
I'm pretty sure you can get that in many other ways varying in degrees of legality, I personally wouldn't pay for something that I can't use unless I jump through hoops to please the person I'm paying to provide me a service. But I also never saw the appeal of watching any sports, much less watching it live so I know my philosophy doesn't apply to everyone and if you want to do that you'll have to settle for either that or some IPTV provider.
No alternatives?
Try spoofing User-Agent string as Windows or Mac. If it doesn’t work, maybe the website requires some feature unavailable by default in your browser that can be enabled, but idk
