How so? I don't have an account but I am able to read the entire paper directly from the OP's link, is there some sort of free limit or something that I have yet to hit? I get some banner ads served on their site but I'm not seeing how it isn't open access.

Researchgate has nothing to do with OA. Its a social media page for researchers. OA is open licensing that give the reader the rights to download, distribute, etc.

You may be arguing that ResearchGate allows free access to its articles in general. If so, I believe there's a logical fallacy in your argument. But I've been warned that naming that logical fallacy is a ban-able offense on HN. (Surreal but true.)

Ah, gotcha - yes that explains my misunderstanding. I was equating "open access" to free access to the content via website. Thanks for clarifying.

Some content on ResearchGate can be downloaded for free. Some can't.
