How did Cyanogen screw over phone makers? really I don't get how an alternative OS who gets limited to no support from the phone makers could possibly screw them over. Wasn't it the phone makers who started locking the boot loaders?
Not saying they didn't I just have never heard that.
I really doubt many manufacturers ever thought people would be using microSD cards for swap on phones that normally do not use swap at all. So yeah that is definitely outside of "normal use" situations.
