My point is simply that Microsoft has to convince the community of their goodwill, and it will take time.

I don't think the existence of other companies with (mabye even bigger) PR problems has any bearing. So what? You want to be equally critical of Uber? Ok. Let's make them prove their goodwill too.

Furthermore, Microsoft is unique in this regard, because at the time of their conviction, they were fighting the browser wars with two open communities: FF and chrome.
