it's not always baseless hostility
Rumour is that Adobe actually produced a *nix native Photoshop years ago. It sold for, well, the price of Photoshop. They then discontinued it claiming that there was not enough interest; it didn't sell cause those FOSS users won't pay for software.
What Adobe didn't bother to mention was that the feature difference between Photoshop and other competitive software did not justify cost difference.
It's not just companies with hurt feelings because of a vocal minority of "code free or die" types. I'd like to see more cases of proprietary software succeeding or failing and why though; the few I've seen, like the Adobe example, failed due to the vendor rather than the FOSS community.
