How is this not exactly helping end-users? Corporations are producers, not users. And no one is complaining about MSFT or any other corporation using OSS as users, but only about co-opting it as a producer.
This is literally why when a company stops open sourcing something, community or other company continues the fork. When a product fails as business and when open sourced, the software itself thrives.
Let me re-iterate, Open Source is purely about the software and the capability to share and make changes. IT IS NOT ABOUT MONEY, BUSINESS, CAPITALISM etc etc etc.
It is not even about collaboration. That is something that came out of Linux development which is one of the most famous Open Source project. All that is necessary is to make the software licensed under an OSS license. And I don't have to get PR from you, I don't need to accept outside collaboration etc etc.
