Yes. I didn't list blender because blender is kind of a unique case. An open source tool that basically slowly became industry standard? That's a 1 in a million from what I've seen. But: as soon as you get professional, like I said, all the plugins and additional software will cause headaches, provided it works at all. The tools I listed there afaik do not have native support / are very unstable on Linux, although I haven't confirmed it.

But yeah I get your point, and it is quite the accomplishment to the blender devs that they made it this far, tho it is not the rule.
