Re: White hats, Black hats, and Grey hats...
Need no hats, will stick to Linux
Linux: no hats here. Cept Red ones.
Oh god run for the hills Linux has exactly the same issues as windows and bsd and osx and os-freaking-two. Humans aren't perfect, the end. Microsoft is extremely competent at hiring some of the best developers in the industry; their issue more relates to management being dumb and having no idea who they're selling to.
I hope that Kaspersky has significant credit for investigating Stuxnet and the Equation Group (NSA?). For that reason it wouldn't surprise if many people recommend Kaspersky to friends simply to support the company.
Most people use Kaspersky (product) because it generally tests the best. This is in spite of Kaspersky (the guy) and his machinations.
Even if the claims are 100% true and I stated why I think it's nonsense on the other article - it's a technical problem with a technical solution that's there for other vendors to find - personally I'd look at it as battle hardening or an indication that the way our software works is broken and do something about it. This is probably why the other vendors at worst have replied with a "meh".
