Re: The last thing we want
You need to decide what group of Linux or open source supporters you are in, with the general options being group 1, you use this and don't care if others do, or group 2, you use this and think it would be better if the general public did too.
If you are in group 1, then you can ignore this. Whether or not this gets developed is not something that you can stop, and if you refuse to use it, then your stuff won't change. There's plenty of Linux software right now, and they're not going to recompile it for Windows only because this would take a long time to build even if they had a bunch of people wanting to and they currently don't.
If you're group 2, however, then you need to understand that you're losing already and no intentional ignoring of Windows is going to change that. Not running some piece of Windows software isn't going to kill Windows, it's going to keep the people who want to run it away from stuff that isn't Windows. If you want them to stop using Windows, then you will have to figure out how to make it possible for them to switch without as much pain, whether that's this or some other type of emulation so their software can still work, finding a workable alternative which already works on Linux, or convincing the people who wrote that software to build it for Linux. I assume you're not doing any of those. I'm happy to be proven wrong.
This attitude is why I'm closer to group 1 these days. I give people Linux machines sometimes, and some of them can and have used those to good effect, but I'm not trying to force people not to use Windows because there are too many problems I can't fix single-handedly and too few people doing anything to try to fix them. There are advantages that we Linux users would get if others started using it, and that's not going to happen as long as we ignore, deny, or as you have chosen in your post, embrace those problems.
