Worst case, Twitter can set up something like "system accounts" that automatically fetch headlines from news websites or RSS feeds and post them with links on Twitter.
If I was a newsie that had an account on a platform that tried to negatively impact the reach of my account on that platform, you better believe I would go out of my way to restrict access to any of my feeds/api/whatevs to said platform. If my account is not okay by their standards for my account to exist unencumbered, why would it be okay by their standards to aggregate via a feed just to get some retention of their users. Capital F that noise
How do you even block one organization from accessing your RSS feeds or your homepage HTML while allowing others to access it? How do you tell apart my requests and Twitter's requests if they both come from a residential IP or a common VPN?
These are companies, they work with the law: put terms of use on your content which ban cloaking your identity. When the unique identifier you put in your feeds shows up on the unauthorized profile, you now have evidence not only that they were illegally using your content but also they knew that and were trying to defeat an access control mechanism.
At that point, all of the big content companies are on your side – none of them are going for a “but we really want to use their content without paying for it!” argument – and it further increases the number of people reconsidering their continued use of the site.
