Re: From the Article
Google, Amazon, Facebook & C. do it with the GPL as well. As long as they don't redistribute code to third parties they don't have to release the source code. All of them use internally a lot of modified code you won't ever see published, even when it's fully used to deliver external 'services'. All open source license were designed against COTS software, just all Xaas models bypass the old delivery method so they are free to exploit open source code and let them publish only what is needed to fully support their business model and profits.
