An argument being made in another social media case (involving TikTok) is that algorithmic feeds of other users' content are effectively new content, created by the platform. So if Twitter does anything other than a chronological sorting, it could be considered to be making its own, deliberately-produced content, since they're now in control of what you see and when you see it. Depending on how the TikTok argument gets interpreted in the courts, it could possibly affect how Twitter can operate in the future.
