I agree that we should criticise two-faced paywalls. We can do this by not linking to paywalled articles in the first place. After all, this is just reporting of a newsworthy event, other publishers exist — or will exist within minutes. (And if there aren't at least two good sources of reporting, perhaps we shouldn't assume it's true anyway?)
It's important to remember that respect for the fundamentals of copyright is a prerequisite for respecting the GNU GPL and other such open source licenses.
