How does MIT build any more trust than a copyleft licence like AGPL? At the very least AGPL stops people "stealing" your work without contributing back their changes?
The poster child for this is chromium which is GPL because it has clear and obvious roots in the old KHTML code of 20 some years ago. In theory you can contribute to Google movement and I suppose some people do but realistically Google controls it completely and they will do whatever they want. even though the source is available it is effectively not a contribution back.
The chrome example actually proves my point, the KDE project, or anyone for that matter, can take the changes Google made to their code. If KHTML was MIT it's likely that wouldn't be the case
