Microsoft bans Free Software on Windows Phone 7

I'm quite confident mickey, that all regulars here know what open source is/means. Since it's also free price-wize I just thought the connection I made was obvious..I was wrong as it seems...so here to clarify:
I was just trying to put myself in 'company shoes' to see what's so bad about open source software that i have to ban it and came up with this:
The worst thing about open source in company terms: I can't charge for it thus my mixed calculations are bound to fail.
Ergo I'm losing money

And have you ever got free software that isn't open source?

Your theory about it all is wrong as free-of-charge apps are still allowed to be published on the marketplace, and I don't know what % of the app sale Microsoft keeps for themself such as Apple keeps 30% of the price, and Google give 30% to the network carriers.

It clearly says on the link in the OP what Microsoft have specifically said. General open source software is allowed on the Marketplace. It's copyleft software with such licenses as GPLv3 licenses, which prohibits the signing of software. Microsoft banned this because the Xbox and Windows Phone 7 hardware only accept code that has been signed by Microsoft, unless the device has been jailbroken.

So they're really just going the same way Apple has gone with a strict app store.

Do you guys think they do that for system stability reasons. To avoid that shaky application code brings the system down like the problem they had with the Vista device drivers.
