This is a disingenuous generalization.
So yes, sharing the article is important in this case. If there was, say, a 300$ per year global subscription to a 100 of publications, I'm also sure 90% of hacker news would buy it.
No one is going to pay $300/yr to read news articles online.
But even people do that, by your logic it's just limiting the access to information to a specific group of those who are able and willing to pay $300/yr to read news.
That said, this is a valuable service. If I were ever willing to consider turning off an adblocker anywhere, this would be where I'd start.
If a link is posted here and requires a subscription, how does that further the conversation you are intending by posting the link?
I want real humans paid for their efforts! If that is the primary concern then we shouldn't be posting non-public links into a public forum for discussion?
Personally I am for anything that can decouple advertising from reporting. There are just too many perverse incentives that it creates.
IIRC one of the sites still has a “buy me a coffee” link, as if the owner needs it.
