This is just yet another of the fifteen thousand arguments covering everything from look-and-feel (remember Lotus?) to copyrights and software patents.
The difference here is that, instead of revolving around the arcane technical details of software algorithms or esoteric legal arguments of business process patents, this one is boiled down to the very basics, and thus clearly comprehensible by almost everyone -- even the legal system. Perhaps we will finally begin to get some clear guidance about what we can and cannot (legally) do.
