I, like the other commenters, installed Yosemite on a third party SSD and it works great. If this were a common problem it would have affected many people and we would have heard about it months ago, back when Yosemite was in beta.
Maybe there is an issue affecting some users, but if so then it is far more likely a bug than some underhanded scheme. And given this blogger's problem solving abilities ("There's a problem... Apple must be trying to harm me!"), my bet is that it's simply a case of user error.
