This is active unpatched currently highly misused exploit vector of GPL and it leads to GPL becoming "shareware" and "bugtest" qualities.
The GPL is not open, it denies potential users to distribute their hard work under a better license.
I suggest we all calm down and do not start another BSD vs. GPL war.
There are several places where you can discuss this endlessly, but please try to keep this on topic.
If you go on, then just try to behave like adults. You know, not acting like zealots.
Oh, please, not this again.
In practice, permissively licensed open source projects do not have any issues with getting corporate contributions. For the most part, the license type simply doesn't matter. If a company is willing to contribute code to open source projects, they do so in a meaningful manner.
Anyway, if there is a license that is frowned upon in much of the corporate world, it's GPLv3. Many companies simply won't touch GPLv3 code with a ten foot pole, if possible, so there won't be any contributions back either. GPLv2 is well accepted, though.
This is also the reason for Beasties to stop attacking Linux. Its open, developers not willing to support your os - port the code yourself, nobody prevents you. Port it in later stages. Stop acting like clown attacking open os, chose a valid goal - try to match own rival - MacOSX.
