It would be cheaper for you but not very profitable for them.
It really depends, there are so many peoole who just don't want more than a couple subscriptions.
The subscriptiin model only favor the giants like netflix, spotify and NYTimes but not necessarily the smaller players.
It's only extra money for them because I'm never ever going to subscribe a monthly sub to a site I read one or two articles a month from. So they're not losing anything from me, only gaining. It's basically free money.
Right now I use archive.ph because I can but if I couldn't (if they make it a hard block) I would just ignore links to said outlet.
I sub to a few outlets which I read daily. But I couldn't possibly sub to every single outlet I see a link from. And I wouldn't anyway.
However if I could click '€0.50 to read this article' then yeah I would if it seemed interesting. Especially real journalism, not reuters copy/paste.
And for a regular reader who reads said site daily, it still makes sense to take out a 10-20 bucks a month sub. Still cheaper than paying per read.
