The same Heather Meeker that started the whole "let's relicense FOSS projects with confusing non-FOSS licenses because we don't like that AWS is using our code"-buzz that's been debated a lot lately.
This also means that if we gave her really bad direction (for the community or project), she would also be fantastic at it. The fault there lies in the direction, not the legal advice.
Depending on what she is doing some people have moral objections to her work (as you appear to), and to what they see as moral flexibility on her part.
But in the end she is a great lawyer who understands this stuff very well, and tries to help her clients understand how to achieve their interests/goals.
That is very separate from whether those are good goals/not.
I'm not sure how that's a contradiction. Of course she can start something while doing her job.
