I’ve already opted-in to the transfer. Delicious for me is basically a collection of everything I’m linked to on Twitter. I don’t put any important bookmark on there—they get linked to from here, go to Instapaper if they’re articles, or get saved to Pinboard.
But the offending paragraph seems to be § 11, ¶ 1:
You agree not to do any of the following: post, upload, publish, submit or transmit any Content that: (…) violates, or encourages any conduct that would violate, any applicable law or regulation or would give rise to civil liability; (iii) is fraudulent, false, misleading or deceptive; (iv) is defamatory, obscene, pornographic, vulgar or offensive (…)
That fourth point is pretty vague about what it means by “defamatory” and “offensive”. The Hacker News thread about the article has some nice input as well. Nevertheless, it doesn’t affect me—and most probably you—too much either way. But it is something to keep in mind (and maybe consider moving to Pinboard if you aren’t comfortable with this change).
