This is no joke, apparently MS joined the Linux Foundation.

What do you guys think? Discuss!
Well, i'd say that M$ is looking for some profit opportunity, as usual btw (nothing wrong with that in this Trump's era).
Regarding the virus-like stuff, unfortunately nowadays almost every big company does it in total impunity, and there's seems to be no solution in the near future (say 30 years or so from now). Only to name a few like Google, Facebook, etc, etc. My advice, be a bit suspicious before joining their widely advertised as open communities (including open source code), because very often it is just an "under the belt" trick.
However, M$ is, as a matter of fact, a lot more better structured organization unlike the Linux folks. So in general, we might expect some Linux's products quality improvements.
