Clause 2c of GPLv2 is close to fail the DFSG, but passes. Clause 5d of GPLv3 is worse (since it's more restrictive, being extended to more cases), and hence it's even closer to fail the DFSG.

There is no qualitative difference between the two clauses. We have never treated quantitative differences between licenses as relevant to freeness. Would you claim that the GPLv2's "make the source available for three years" requirement is ok, but a clause saying "make the source available for six years" is not?

I think you are talking about clause 3b of GPLv2, aren't you?

Maybe you picked the wrong example, because clause 3b is a non-free restriction. Fortunately there's another alternative option, represented by clause 3a, which is DFSG-free, and consequently GPLv2 is acceptable.

No, again you have misread the DFSG. 3b is DFSG free, because the DFSG says the GPL v2 is free. Debian currently uses 3a because it is much less effort, but that doesn't mean that 3b is non free.

Hmm, that's not a universally held opinion within Debian. I don't know if I would consider a modified GPL that only offered the 3b option to be free; I suspect I would not. So even though GPL itself is free, that doesn't mean that any element of the GPL taken alone is also free.

And it wasn't my point to try to claim that 3b was free, my point was about whether quantitative differences should impact our decisions about the freeness of two otherwise identical licenses. Apparently I should have picked a better example.
