The accident was that the plan was conceived by Stallman and involved GNU/GPL.
What I'm saying is a similar plan with BSD/MIT licenses, if it was initiated by another guy first, would be just as good.
In other words that the reason GNU/OSS got that far was that they provided software people needed at the right time -- not because they were GPL as opposed to BSD licensd.
Was makes you so sure that it would matter? The original software will still be there and free for any modification one would want to do.

Apple famously doesn't provide any "recent" GNU tools because they're GPL3+ licensed, when they were previously GPL2.x and less restrictive.
Maybe, as a data point: how many of the manufacturers' contributions to Linux are MIT licensed, so that they can be picked up by *BSD as well?
