This is a capitalist society. Software development is not some sort of pseudo-religious philosophy. It's about making money. When will the GPL nuts understand this?
Correct. This is why many software development teams are forbidden
to look at or use GPL'd software during the software development process, because of the fear that the developers will be contaiminated, therefore, letting them possibly incorporate the GPL code into the propiertary software. If anyone finds out the software developers were contaminated and did in fact incorporate the code they could be sued the FSF, etc. That's very nice of them isn't it? With the BSD, the true open-source license, all of this is avoided.
This is for the most part incorrect. RMS loves IBM, therefore, he really has no beef with AIX (at least I haven't seen it). As for Solaris, I've made it apparent that he does not like Sun. Plan 9 is now under a BSD license. If he criticizes that, he's just making an even larger mockery of the open-source movement. I haven't seen him criticize Linux lately; however, I believe I've seen it before. To criticize your own followers is pretty stupid. He wouldn't make a very good politician/businessman would he?
