MongoDB only needs the Linux kernel/GNU/GCC when it's running or compiling on Linux. On OSX and Windows it uses other toolchains.
And your point goes against the entire spirit of open source. No one should be forced to contribute back to open source less they be criticised by the community.
Good call. They should also be contributing back to those toolchains.

That right there is what we call irony. This is precisely what Mongo is trying to do.
That makes absolutely no sense.
What they're trying to do is make it so challenging to host MongoDB as a service that cloud providers can't do it. They implemented it with an absurd requirement forcing contributions to open source, but the intent is not to improve open source, it's to end regain market control.
