I run a website. I can pay Google, MS, Meta, etc money to make my site show up higher in search results. Or gain an audience through SEO and organic growth, including on social media. I'm happy when someone shares a link to it, because that means more eyeballs on what I'm putting out. Then I can choose if and how to monetize it. By suggesting that this harms the publisher makes no sense. Why would anyone ever pay for Google sponsored search results if it's harmful to their business?
The lobbyists and politicians have framed it as "using" or "stealing" the content, which is an outright lie: reproducing content without permission is already covered by copyright law. Many of these news sites even have abstracts and social cards specifically for preview when shared.
The other analogy I like is "journalists drink coffee when writing. Starbucks has lots of money. Let's force Starbucks to give journalists free coffee, and a dollar out of their till whenever a journalist walks in."
It's backwards! Offensively so!
If these publishers didn't want their content on Facebook or Google, they can use paywalls, robots.txt, or referral blocks to stop it showing up. But none did - they just wanted to bite the hand that feeds for a few bucks, and we see how well that worked out for them.
