I imagine their bounce rate will be very high if they continue doing this. Other news sites have done similar things such as make you participate in a survey before reading the article. In order for me to open this article before September 22, I would have to copy that link, paste it into an email to myself, open Mail on my phone, and open the link from my own email.
Don't bother, on the 22nd, it will probably be one of the top titles on Hacker News: "Remember this article that used to be exclusive on Apple News? Now you can read it!".
this is but another social experiment/AB test/growth hacking thing (and I'm giving them already valuable data just by posting here).
