I also didn't claim that. I wasn't comparing WSL to other virtualization solutions.
WSL2 is cool. Linux doesn't have a tool like WSL2 that manages Linux virtual machines.
The catch 22 is that it doesn't need one. If you want to drop a shell in a virtual environment Linux can do that six ways through Sunday with no hardware VM in sight using the myriad of namespacing technologies available.
So while you don't have WSL2 on Linux, you don't need it. If you just want a ubuntu2204 shell or something, and you want it to magically work, you don't need a huge thing with tons of integration like WSL2. A standalone program can provide all of the functionality.
I have a feeling people might actually be legitimately skeptical. Let me prove this out. I am on NixOS, on a machine that does not have distrobox. It's not even installed, and I don't really have to install it since it's just a simple standalone program. I will do:
$ nix run nixpkgs#distrobox enter
Here's what happened:
$ nix run nixpkgs#distrobox enter

No steps omitted. I can install software, including desktop software, including things that need hardware acceleration (yep, even on NixOS where everything is weird) and just run them. There's nothing to configure at all.
That's just Fedora. WSL can run a lot of distros, including Ubuntu. Of course, you can do the same thing with Distrobox. Is it hard? Let's find out by using Ubuntu 22.04 instead, with console output omitted:
To be completely, 100% fair: running an old version of Ubuntu like this does actually have one downside: it triggers OpenGL software rendering for me, because the OpenGL drivers in Ubuntu 22.04 are too old to support my relatively new RX 9070 XT. You'd need to install or copy in newer drivers to make it work. There are in fact ways to do that (Ubuntu has no shortage of repos just for getting more up-to-date drivers and they work inside Distrobox pretty much the same way they work in real hardware.) Amusingly, this problem doesn't impact NVIDIA since you can just tell distrobox to copy in the NVIDIA driver verbatim with the --nvidia flag. (One of the few major points in favor of proprietary drivers, I suppose.)
On the other hand, even trying pretty hard (and using special drivers) I could never get hardware acceleration for OpenGL working inside of WSL2, so it could be worse.
That aside, everything works. More complex applications (e.g. file browsers, Krita, Blender) work just fine and you get your normal home folder mapped in just like you'd expect.
Sure, but I never claimed otherwise.
