If this is triggered on any modification, then "private" modifications aren't so private anymore. Neither the OSL nor the AGPL make such a requirement. However the Cascade Open Software License (or whatever it was that was brought up on the list a couple weeks ago) purports to do this in a statement summarizing the license even though it is not clear how the license aims to achieve that goal.
<br><br>My own views are that forced distribution licenses such a the AGPL and the OSL are problematic from a FOSS development perspective but I would not quite go so far as to say they shouldn't be called "open source" (note that no version of the AGPL appears in any list of OSI-approved licenses, however). I do think there are excellent reasons to avoid such licenses however. We should probably start a separate thread for that :-)

I would draw the line at any license which requires private modifications to be distributed to the original developers-- those should not be subject to OSI approval.
