I disagree with your assessment that people are more acceptable. I think it's just more along the lines of the people that care are "over it" and have learned their lesson now.

Those that genuinely care about the free software movement either have or will stop contributing to these projects and stop signing CLA's[1] so their work can't be abused in the future (turned into a proprietary product).

I personally don't think there is much more to argue about.
