If you paywall important news, everyone will share free articles instead. Does the birdseed press ever paywall?

Edit: compare https://www.lemonde.fr 's cookie/subscription wall with https://www.thesun.co.uk

Thanks for taking the time to answer. Yet I fail to see how this answers to my question (I must be dumb):

"why paying for unimportant news?"

(edit: I don't get the policy from "Le monde" either. For example I see some important news which are paywalled, while other important news are free. Same for unimportant news. It seems the categorization is quite done at random (at least in what I read today).

If you take "Les echos" it's clearer, important news are paywalled, which I find more logical as a business model.)

I won't speak for Le Monde's commercial side, but think the concept is that a subscriber considers themselves as paying for all the news; accepts any "freeriding" on important news as a cost of generating the public good of an informed society; and leaves it to NARGs (should any exist) to account for the value proposition differently.
