Is the policy not from a place of bad intentions? It's clearly a ploy to try to trap users on Twitter, preventing them from promoting their presence on alternative platforms.

Is it not vague and poorly worded in a fashion that could give the impression that sharing links to other platforms might be prohibited? Is this ambiguity perhaps a feature and not a bug?

I find faux-free-speech supporters rely on ambiguity to mask their actual intentions. I would much rather people focus on asking more explicit questions and requesting explicit answers.
