This is totally different from "it only works if all of the platforms you use do this." That's a collective action problem. One which does not present itself in this case, where marginal actions produce marginal benefits.
What you're now saying is the marginal actions (and thus benefits) may be bounded. Which, sure. But that also doesn't change if all the platforms "do this," but boundedly.
For OP, Twitter might have been the holy grail and they’re now cool, but maybe not if there’s $x others that have already rolled over.
