Hardly. It's a practical view and a view most businesses have to take in order to survive. No one is going to do your work for you. You have to make contacts and build partnerships that mutually benefit both sides. Start a business then sit back and wait for other businesses to contact you, see what happens. You'll have to close your doors within a month. This is especially true when you have strong competition. When your rivals out-work you, it's your own fault. When potential business partners skip over you because your rivals create a more compelling environment, it's your own fault.
The idea that third-party developers and publishers owe any one console manufacturer is a childish notion. In a business, you are responsible for yourself. No one owes you anything unless it's written down in a contract.
Yoshida also said, "There are limited resources that third party publishers have, and they have to diversify into new areas constantly; that's a challenge to get the support that we want." That means you have to fight to get support, which is the way it should be in an open market.
This is true only to an extent. 3rd parties are going to follow the sales. They like Sony because Sony has weak 1st party, and they'd love Microsoft if MS consoles sold better because MS 1st party is nearly irrelevant on their own platform.
However, let us keep in mind that "3rd parties" aren't a single entity, but multiple different players in the market. If Call of Duty breaks sales records on Xbone, it's not helping Square Enix to sell Final Fantasy any more than Mario Kart sales on Wii U, so the only thing that the publishers can follow is the console sales.
What this means is that the best way to have as good third party support as possible, is to sell as many consoles as possible. Even if you'd let 3rd parties dictate your platform, they're going to leave it all together if their games do not sell.
