I absolutely agree with you, given the choice and the ideal world, I'd much rather live in a fair system where companies compete on the things that actually matter. Absolutely.
I just think we're fooling ourselves if we think that we can simply expect people to adhere to this with no tangible incentive, rather than build a system which has the desired result.
In other words, it's still the system that's broken. There are a lot of companies I'd like to boycott (and I certainly boycott and disagree with Apple's decision on this specific matter), but I don't blame the companies for trying to make money—regardless of "fiduciary duty" which is pretty irrelevant (I was just talking about the nature of companies to make money and dominate the market if possible; this would be true of any company, not necessarily just public companies with duty to shareholders).
This is a tough call, and I'm sure it was tough even for Apple's legal team. Is it worth tarnishing their image to attempt to hold a competitor from the market for another couple months? Looked at from a strictly logical standpoint, with profits enabling more technological developments and more production capacity, as well as more advertising and sales efforts, it just might be worth it.
You know that a whole team debated this and did dozens of calculations and eventually the call was made, but knowing Apple, this was no butt-hurt matter of principle. This was a market decision based on something they could do that would be beneficial for their company in the grand scheme of things.
Do I agree? Not really. I think the company's reputation is way more important than this injunction. But it's an exceedingly complex decision, based on many factors that I don't have information about, and they made a different decision. I honestly can't blame them for that.
It's easy to answer my question with a simple "yes." It hurts you. It doesn't feel right. Companies shouldn't be so impersonal. They should play nice. I know. We need to fix the system that allows despicable acts like this. But in the context, it makes perfect sense. "Blame" is not addressable here except to the system. (As is usually the case, but that's for another essay...)
