Twitter has denied that it is a publisher in court. It is a Common Carrier in effect, and has benefited - to the detriment of its competitors - from common carrier protections.

Any time Twitter has been called to account for what it publishes, it claims it's not a publisher. Give them what they want.

They are a platform distributing UGC protected by the CDA.

Any discussion of “common carrier” is entirely orthogonal, and basically nonsensical in the context of something like Twitter.

“Common carrier” generally arises as a trade-off for a government granted monopolies based on limited access right-of-ways. This was true for railways, and true for telephone wires. Why would this apply to a random service like Twitter?
