Weird, why do they only say "not for Linux" on the site
WTF is weird? That is a download link, and there is not a version for Linux of any kind yet.
Could they say something else? Sure. But that does not make what I see as weird.
Especially as you don't see that on any other OS.
I just find it weird that you go to the download site to see if it is available and instead of promoting the product, they shoot you down. They don't hint that you should look into it more, or check back eventually.
They are already promoting it to almost 98% of everyone. I'd say they are covered and won't lose out over waiting a little longer to announce something to way < 1%.
