i think there may be some conflating of "very powerful" (?) with monopoly here.
it does not take much effort to realize that twitter is not a monopoly in the space of speech platforms. it's not clear to me that twitter is particularly unique as a speech platform: blogs minimally could serve this role, as could mastodon. more controversially perhaps: facebook/instagram.
contrast that with a situation where you literally /cannot/ get utilities delivered to your house because the utility company doesn't like you: seems like a fairly stark difference to me.
