There were much better blog posts about Macheist with less speculation but more wisdom. Also, several developers of the bundled apps not only said they were content, but raised points like long-term profitability and that a the vast majority of the purchasers would not have bought their app on full price.
I would also add that some of the apps needed the publicity to a) prepare the soil for a major update and/or b) fight off hard competition.
Gruber ignores all this and focuses, with numbers which he seems to be confirmed by repeating them, on the question of fairness.
But this question can only be answered by the developers themselves.
And if they feel cheated, Phill & co. will not have much success with future projects, so sooner than later, the market will regulate everything anyway. No need for daring avengers of the innocent.
So in the end it's nonsense to get all agitated about this issue. Especially not when you don't know the numbers.
As for attention-grabbing, I don't know if this is really the case. But I think that daring fireball discusses too many issues that help nobody. Is OmniFocus vaporware? springs to mind. Also, the tone seems to get rougher, more confrontative.
No surprise then that people think he writes for maximum attention.
I still like his site, but less and less.
Fairies wear boots and you gotta believe me!
