Think about it, you are paying for a statue that Nintendo is artificially making a demand for and locking away content on disc. Everyone seems to ok with this and it's because it's Nintendo doing it everyone seems to be alright with this. Don't mistake Amiibo's for the same as Skylanders and Disney Infinity. Because they only apply for one game. Amiibo's have locked away content on most games they appear on. This is not acceptable.
I don't see any outrage regarding the Amiibo's, in fact people are happy about them and want to buy them left and right(including many of the staff on site). It seems to me that people love Nintendo too much and don't criticize them for this practice enough. Not making enough statue's and then apologize for it is unacceptable. Don't apologize for things you can do something about. They have no excuse that is valid for not making enough Amiibo's to satisfy the market and its demand. Fix this Nintendo!
We also have the issue with them locking on-disc DLC only for those who actually buy the Amiibo's as well. This is not a practice we should support as consumers. If there's content on disc that's locked away, there is something wrong. Capcom, Bioware and other companies have heard it from the consumers about how upset they were about this practice. Unfortunately this is a trend where people keep buying into bad consumer practices and award them for it.
What I am trying to get across is that you should know what you're getting for your money. When you give your money a company for a product, you're agreeing with the product and the practices around it. You are also saying that you want to spend money on that product and get similar products like that in the future. At the end of the day, your wallet is the most powerful tool to vote with in a consumer market.
