What if you really wanted to access that content? Previously you could click on the "no thanks" link and keep going. Now you'll be forced to install their app.
I don't really want to access that content, by definition. I've always said that. I use Adblock, and it's trivial for websites to detect that and make it difficult to view the content. I fully support their right to do so, and if they do, I'll just close the tab as soon as I realize there's no content there. It's really not a problem.
Someone at work sends you a link to the WSJ asking for your comments on it (a thought piece on a competitor? who knows). The WSJ is now available only through an app. How do you deal with this?
A hypothetical, but your web experience could become collateral damage as well.
Read it later when around a computer, perhaps?
Sending links to protected content is considered bad manners, even if only registration or login via Facebook required. I would ask that person to send me printed PDF copy of that article instead of link.
I say "I cannot read anything on that link you sent me."
