The only reason why the "Linux community" cannot create adequate FPGA design tools is that the "Linux community" is completely inadequate in comparison to what's needed.
Reverse engineering tools are pretty good these days. I have no doubt that a dedicated hacker could sit down with Ghidra and the free Windows version of Vivado for two years and come out with something that compiles FPGAs well enough. But there's a shortage of the kinds of people who would do that, they're all busy doing other things, so it doesn't get done.
More easily, someone could get the free Windows version to run on Linux. If it doesn't already work in Wine, they could figure out and implement the needed Wine patches. If Vivado has a DRM scheme they could break it (potentially very difficult), if not then it should be straightforward. Nobody seems to be doing that, either.
The same applies to things like the Nvidia drivers.
In the past, freedom RE projects were handicapped by needing to maintain a Chinese wall. Now it's become obvious you don't need a Chinese wall, you can just straight up decompile someone else's software and use that as a reference as long as you don't copy it directly and you don't make it too obvious to the copyright owners what you're doing. Keeping your anonymity for this sort of project is easier than ever before too. Yet we see less freedom RE projects, not more. Why is that?
Because most don't want to work on something big, with a high risk of being sued into oblivion once released?
It's a pretty low risk if you don't put your identity out there. I know there's at least one Git forge that's a Tor onion service. Even on GitHub 99% of the time this ends with a DMCA takedown of the repository. You should probably put it on a pseudonymous alt account but you don't actually need to use a Tor onion service.
You could also get someone else to put their name on the web hosting and so on. Don't know who exactly, but there are a lot more people willing to take legal risk of having reverse-engineered an FPGA toolchain, than people who can reverse-engineer an FPGA toolchain. Doing the work is what's most important, and the rest can be figured out later. But you don't even see that. You don't see people being like "I reverse-engineered Vivado but I won't give you a copy because I could get sued."
"Doing the work is what's most important, and the rest can be figured out later."
I would say for most people his means they won't start the work if they don't know whether there is a way. Also most people like to get credit for their work. So the number of people capable AND willing to work without getting credit is low. And that is not surprising to me.
It is not my skill set, but I certainly would not invest much into something like this.
