I think you misunderstand what 'dumping' means in this market context. Sure, free software like Linux is great. But if you didn't have that preconceived notion, a competitor dumping free software on the market to make others' initiatives unprofitable would look like an anti-trust violation, rather than a charitable act of community.

I understand perfectly fine. I think your statement however is quite ignorant about the state of things at the time these actions were taken.

Do yourself a favor and research a little bit.
