How can Sony (home) consoles sell more on average than Nintendo (home) consoles if Sony steals Nintendo's ideas?

The reason Sony's consoles sold more has nothing to do the ideas Sony has stolen from Nintendo and everything to do with the mistakes Nintendo has made.

The first being that Nintendo controlled third parties with an iron fist when they were dominant. It's no wonder many were willing to jump ship when they had the chance. I'm not 100% sure why they didn't do it with Sega but maybe they were just much more confident that Sony would be successful given their reputation at the time.

The second is Nintendo being a victim of their own game sales success. I mean there's a thread on here where some people are fapping at the idea of Gran Turismo 5 passing 10 million (after price drops and bundling mind you) when Nintendo has had dozens of games sell well over that with many never seeing a price drop for years. They simply never had to rely on third parties like Sony does. Imaging how the PS3 would have done if it had received the same support the Wii had. It would have been dead because Sony can't carry a system with its first party games, you can just look at the Vita to see that.

I also think that the Wii actually did some serious damage to Nintendo in the long run even though it was so successful. I think it gave Nintendo the idea that it didn't major third party support at all or that third parties should either come or it's their loss which might have lead to a widening gulf in relations. It also gave Nintendo the idea that hardware specs no longer really mattered when they still do since it requires more effort for third parties to make games work for hardware that is significantly less powerful.

Another reason is Nintendo marching to their own drummer and because of that they've been slow to react to many of the things their competitors are doing. Their online isn't even up to what the competition had this generation let alone what it will be like in the coming one. That coupled with the fact that they seem unwilling to actually moneyhat any major AAA third party games (at least for Wii U) makes it unlikely that we'll see any serious challenge from them this generation as far as going after the core gamers that weren't already interested in Nintendo's traditional games.
