It's just a minor policy change on the Microsoft Store which says you can't create an "app" for a free open source product as if it's your own. So, you can't create an app of Ubuntu Linux and charge $5 for every download on the Microsoft Store.
Reasonable. Sound.
“Does the GPL allow me to sell copies of the program for money?
Yes, the GPL allows everyone to do this. The right to sell copies is part of the definition of free software. Except in one special situation, there is no limit on what price you can charge. (The one exception is the required written offer to provide source code that must accompany binary-only release.)”
On the other hand, there’s https://www.gnu.org/licenses/gpl-faq.html#DoesTheGPLRequireA...:
“if someone pays your fee and gets a copy, the GPL gives them the freedom to release it to the public, with or without a fee. For example, someone could pay your fee, and then put her copy on a web site for the general public.”
App Store rules may make that difficult to do for the buyer.
If there is nothing legally stopping them from doing that, then how is Microsoft going to arbitrarily enforce these new rules?
"Neither the name of the copyright holder nor the names of its contributors may be used to endorse or promote products derived from this software without specific prior written permission."
But Microsoft's store is a private marketplace (despite costing nothing in dollars to use/view). They can make whatever rules they want for the software they distribute or allow to be distributed there. First amendment, etc. doesn't apply. If Microsoft decided only software with unicorns and bunny rabbits could be distributed on their store, they are pefectly within their rights to mandate and enforce it.
I don't care if microsoft's store is a private marketplace. People should have the right to run whatever programs they want on their own hardware.
IANAL, just asking the question, I might be super wrong.
