That's such a weird comment considering gnome has been the on the forefront of wayland's implementation from the get-go and KDE's is still experimental.

Using wine can be a bit troublesome especially if you're new to linux. For example wine doesn't come with dxvk which is basically mandatory for playing games nowadays.
Most people use another program to deal with wine, like lutris, bottles, or steam with the built in proton.
X11 does not support different refresh rates across monitors.
You need a Wayland capable DE for that. The big one is Gnome.
There's like at least one xpac coming down that will somewhat revitalize the game, support won't end tomorrow.
This is just blizz squeezing for more money, like every other game with an MTX shop.
There's no such thing as using the internet safely.
Packets you send can be intercepted.
Websites you browse serve ads with malware.
You can be hacked.
All of these are made easier on outdated OSes.
In these days of GAAS they won't let you run old versions of their games because of $. They want you tied to their launcher, advertisements and whatnot.
There's just no reason not to update your OS. Old devices run perfectly well on linux with its lower memory footprint. Running an old, unsupported OS and connecting to internet is asking for trouble.
Sadly this is then going out of their way to stop people with old OSs from playing their games, even though they would still technically run.
There's not necessarily any malicious intent. Some features require breaking backwards compatibility.
Supporting old platforms is bad for everyone, it locks out stuff and takes dev time. People need to learn to update their OS.
I wouldn't call it bombing if the problem is legitimate, and server issues on an online game is definitely a big problem.
