Didn't buy Captain Toad, and probably won't unless I can find the Toad Amiibo. Not sure if I'm buying Kirby on Wii U either, since I can't get DeDeDe or MetaKnight at anything approaching reasonable cost/effort.
Not buying Splatoon, not buying Codename S.T.E.A.M., have enough backlogged Fire Emblem that any content unlocks requiring impossible to find Amiibo figures would prevent me from buying it either.
I'm a Nintendo fan, but that doesn't mean I need to buy everything they put out there. If they put out content that is aggressively anti-consumer, as a consumer I'm going to choose not to support it. Does Amiibo cross that line? At this point, I'd say you could argue either side...
The Animal Crossing cards were pretty easy to find (and were even sold on N's webstore for quite a while.)
They disappeared from retail locations very quickly here, and were never restocked. (Retailers told me they tried but weren't able to get more in - maybe they were lying, who knows?) It's true you could buy the cards online from Nintendo's website, but they weren't well advertised and (at least when I saw them) not all series were available there.
Surely even you, a staunch fan and collector, can't defend how Kid Icarus cards were handled in North America.
The point remains: it shouldn't be this hard. When things are successful and people want them, and Nintendo makes a profit from selling them, it shouldn't be so difficult to make them available.
