Excellent piece, indeed legal is not the same as legitimate. More often than not the law is lagging behind and things might be wrongly "fixed" at a later date. In that interval that's when our communities need to build its own tools to protect the commons. We're clearly reaching such an inflection point. Interestingly, I think there's is a difference of reaction between the people with a Free Software culture and the ones with an Open Source culture.
Or why focusing on the practices will likely lead to cargo cult and you might never reach the real benefits. Don't mimic other organisations, think about the underlying philosophy.
Aligning people with differing core values in a team is indeed necessary but difficult. It can kill your project for small teams, for larger teams you will likely need to think your organization keeping the misalignment in mind.
I'm not sure the "bubble" comparison properly applies. Still there are indeed signs of the Open Source movement getting in troubles. It'll be all the more important to stick to the Free Software values.
The interview is overall very interesting (I advise listening to it in full). It's nice to have such an historical perspective. At 15:00 there's a question which prompt a very important explanation of why the word "over" was chosen and repeated in the agile manifesto. Unfortunately it's been often misinterpreted...
Good and reasonable advices... doesn't make them easy to truly apply though. It's likely worth trying to live by them still.
