Excursions by Amit Gawande

(…) expanding a license’s requirements beyond derived works is not entirely new; the GPLs requirement that build scripts be released is one example. But this takes that requirement to a rather different level, to the point of, Garrett suggested, even requiring a relicensing of the Linux kernel if a MongoDB service runs on Linux.

The change in licence terms sounds too stringent — far beyond just the scope of derived works which is typically the case. MongoDB can very well stop calling itself an open source software then when to use it in any significant manner, one needs to get into a proprietary license agreement. Wish the license doesn’t get approved as a valid open-source license.
