A day or two before he posted the list, he had to go through a run-around with some dude who apparently had copied a whole bunch of his (10 years+) blog content to their own, no attribution, nothing. I believe he deals with this type of thing frequently. I also think this tools list is a popular item for such "re-blogging,"

In this particular case, it appeared the offender simply didn't understand proper "nettiquette" and once pointed out, promptly removed the content (although he appears to still have a whole bunch of OTHER people's stuff copied up there, so who knows?).

I don't see any issues with it. He's trying to preserve credit for a work he created. Yes, even a blog post like this one is work. In the past, some of Scott Hanselman's has been ripped off. I think it was a talk or post about working from home, or something related to how to be productive.

No - copy and pasting is endemic, and if he wants to keep a list that's his (rather than have it shared on 50+ 'latest might-get-ad-clicks content' websites), then good for him.

But his appeal will not stop those copiers, and it does annoy his intended audience.
