Why Nintendo is so stubborn when it comes to media formats?

For the N64 Nintendo was actually developing the 64DD which was meant to be released a year or two after the N64, with carts being only a stopgap solution. For some reason they couldn't get the thing ready in time, so the N64 was stuck with carts. The 64DD used its own magneto-optical media developed by Nintendo partly due to fear of piracy and partly because they didn't have a partner who could offer them CD technology, as the deals with Sony and Philips went sour.
For the Gamecube it was because of the design they made for the console. I don't know why they are so focused on small.
The Wii and Wii U don't have DVD playback purely because Nintendo doesn't want to pay DVD and Blu-ray royalties. At this point, it's not a big deal.

I believe it was because of piracy. Here in Brazil PS2 dominated console-wise, but i didn't knew 1 friend who didn't used pirated games. It was really easy and some of my friends had over 500 (i'm serious) games, all bought for $2 each. It was crazy.

Maybe it payed off because Brazillians today really like the playstation brand, but i can see why that scared Nintendo. 

Everyone I knew who had a ps1, ps2 or psp has lots of pirated games. I think it really sold a lot of consoles on the fact that games could essentially be free after a small mod. And now the brand is set in people's minds
