I don't know if you can even call it cynicism anymore. You just understand the news media business model. Outrageous headline -> more clicks -> more ad revenue. There would simply be less revenue if your friends only had to read one article to get the full picture.
Even if you mark it as such in-app; as a business you still have a legal duty to correctly report the income your business made.
Not doing so is already illegal. This just helps the IRS catch this type of fruad easier.
There's no extra taxes or anything - the $600 or more is taxed when reported correctly (as it was before this change, and how amounts under $600 are taxed as well - business income).
When you go to pay someone, there's a pretty big box on the screen that says "Are you paying for goods or services? Protect your purchase here" with a little toggle button, and an explanation that the seller will pay a fee in return for you being able to get a refund.
Somehow people have become convinced that reading a stream of half-sentence headlines is the same thing as being informed about current events.
