It makes me sad to realize that it was possible that the GPL was necessary to bootstrap free software culture and that we no longer need it now that we've won.
One large side of the industry is turning to managed services. They run free/libre software, but build lock-in on higher level and avoid giving direct contact.
On the other market, the desktop free/libre software won as with Android and free/libre parts of MacOS/iOS.
However they don't do that to benefit the free/libre software in any way, but for getting software cheap or even for free.
The amount by which this flows in one direction, there isn't a win.
MIT and BSD predates it, and GPL only had a go at it for two reasons:
1 - Sun decided to inovate by spliting UNIX into user and developer SKUs, thus making the until then irrelevant GCC, interesting to many organisations not willing to pay for UNIX development SDK.
2 - AT&T tried to get control back over UNIX's destiny, and made BSD's future uncertain
