My post was, first and foremost, about resolving their issue. Not only have I pointed out how to read the article, I even provided an alternative method in case that didn’t work for some reason. I also asked for clarification on their problem, in case I could help further.

Only secondarily was my post about how paywalled links (which again, this one isn’t) are explicitly on topic on HN with the reasoning why (since the OP was asking why they are permitted in the first place). Furthermore, the linked and quoted FAQ continues to explain that complaining about such links is explicitly off topic, with further links that I went through the trouble of including.

I don’t understand how you find that to be “not contributing much”. I can hardly imagine a more comprehensive response to this particular query.
