I would support this if they hard forked to ban all asics. Because why asics should have advantage over a GPU? But then, GPUs have advantage over CPUs, thus Core should also make changes to forbid GPU mining. \s
You missed the point.
The point isn't that the new technique is faster, it is that the new technique is patented.
If it was only faster then everyone else could also go faster to keep up.
But it is both faster and patented, so even if everyone else comes up with the same idea, they still aren't allowed to compete because of the patent.
