exactly.
if he's serious about this he could post a link to a draft version or summary of the article including the data.
i don't think a journal editor could prevent him from doing that.
(or even if an editor could, s/he probably wouldn't make a fuss about it, as long as the draft version contains a proper reference to the printed article.)
Alright, you've inspired a rant. As a disclaimer, it's not you, it's me

My wife & I have a 2 month old baby, and while it's amazing, and beautiful, and wonderful, and all of that, 2 months of wild nights is starting to take it's toll. So, if my tone sounds angry, it's not because I hate the world, it's because i'm just about to... looooose control.
The material is now owned by the journal. They have a copyright on it. If he posts the draft, they would sue him. And, even if they "don't kick up a big fuss about it" and sue him, it's still unethical for him to go against the explicit terms of the contract that are in place between authors and publisher in this case. By deliberately making this material available, outside of the journal that now owns it, the authors would completely discredit themselves as meaningful and respectable.
Honestly, the issue of complaints about a paywall here are nuts. Don't you people understand the advantages accrued by the peer review process? The fact that this power data is published in a respected journal is a good thing. It gives a whole lot of legitimacy to it. It means that not only the reputation of the authors, but the reputation of the independent reviewers and the publisher is on the line. The data presented is a whole lot more legitimate than if it were just uploaded to dropbox for your benefit. This is a huge improvement over the typical internet warrior faceless review of so-called internet experts.
Yes, there are open access peer reviewed journals out there. Typically it costs the author exponentially more to publish a paper in an open access instead of a closed access publication. As they say, the devil always gets his due. One way or another, somebody has to pay for the peer review and publication process.
But, even without paying for the source data or the paywalled jouranl, I already have all of the interaction with it that I would be looking for. In the name of fair use, we have important pieces of the publication reproduced, and interacted with. So for me, this is the best of all worlds, and I applaud the approach.
