Most likely it won't as it only hosts text, and links + individual words is ok

(the reason I'm less worried about Art 11 is two fold: first is that I do agree that content scraping like Google News should be under agreement and that it will be worse for the news orgs than they think it will be)

But in much of the discussion, links are explicitly mentioned.

On the other hand, HN doesn't have ads.

HN doesn't fall under EU jurisdiction, so even if they did violate it, I'm doubt it would be enforced.

So it's not like the GDPR; it doesn't apply if it affects any European, anywhere?

I don't know, but it doesn't matter. If your company runs a US website and doesn't do business in the EU, their laws can't cause you to take action.

I've seen quite a few paywalled articles posted, where someone else posts a link to "theoutline.com" to bypass paywalls, or just straight out copy/paste the article text.
