This huge revolt is interesting but I doubt it makes github very scared. They'll just come out with some new version of it which they'll show takes into account licenses (or uses a 10k or something dataset with hand checked licenses) and that'll be that and we'll forget about all this the week after.
And yet would they have bothered without the "huge revolt"? I doubt it; what you are actually describing is a scenario where the "huge revolt" succeeded.
