Somehow I don't think Xtraeme is shedding many tears over this.
I'm not sure that's really what it is either. I think it's just that Linux has become the new "cool" thing, and people are getting into it for that reason. Additionally, there is growing genuine discontent with MS software.
So I suspect that the popularit of these distros is because the majority of their users are refugees from Windows land, including developers who see more opportunities to develop in Linux. Thus, they're not looking for the Unixy experience that we used to all get from a Linux distro, but for something more akin to the Windows desktop experience.
Although I guess I do agree with @AnachronGuy on the point of those people not knowing anything else. I just think they also don't care about it, because Linux qua Linux isn't what was important to them.
But I don't fault them for it. People have different goals and motivations. One size does not it all, and popularity puts pressure on a distro to forget its own reasons for existence (the vision of the creators) and become more what the crowd wants.
I like what Void is now, and don't care to see it become something else, which is why I came here from Debian. I know I'm a minority in the world. So I like Void to stay for people like me, so I don't have to go somewhere else.
I'm greedy that way
