You can actually effectively kind of do that by getting an Apple News+ subscription. That's $10/month and includes WSJ articles.
If you are reading on an iPad or iPhone and see a WSJ link on HN, hit Safari's share icon, and select News and it opens in the News app.
Edit: this is kind of interesting. I looked at Bloomberg and a few others and the subscriptions were comparable to their normal digital options. But WSJ is much cheaper on Apple News, why is this so? Is there some catch (like 2nd year is expensive)?
I have no idea. I mostly got a News+ subscription for the magazines. It has Scientific American, Consumer Reports, National Geographic, Popular Science, Popular Mechanics, Smithsonian, Wired, some Mac, Windows, and Linux magazines, Time, Newsweek, The New Yorker, Readers Digest, The New Republic, National Review, The Advocate, and a whole bunch more in a whole bunch of categories.
I only regularly read a few of those, which is enough on its own to justify the subscription. Having all the rest there for when I occasionally want something different is a nice bonus.
$37/month is high for a news source I usually read less than 5 articles per month. I already pay for Bloomberg/Economist/NYT/New Yorker but that’s because I regularly read double digit number of articles from them per month.
At the same time when social media (like hn) sends me to wsj I would gladly contribute proportionally to my utilization.
