As far as crackdowns becoming more popular goes, it might well be because we saw the release of two high-profile games recently, AM2R and Pokemon Uranium. I could easily imagine that other fangames didn't get backlash from nintendo because they didn't get as much attention, and they're just retroactively cracking down now. Granted, Iwata being a leading figure for a long time probably had some effect as well, but despite his own views, legal departments often just do their own thing.
Regardless of the games being not sold for money, it's not exactly kosher. Honestly, it's kinda surprising that they stayed up as long as they did.
