Trying to define "all" is an impossibility; but, by virtue of having taken no action whatsoever, answering that question is irrelevant in the context of this particular judgment: Tiktok took no action, so the definition of "all" is irrelevant.

In general, judges will be ultimately responsible for evaluating whether "any", "sufficient", "appropriate", etc. actions were taken in each future case judgement they make. As with all things legalese, it's impossible to define with certainty a specific degree of action that is the uniform boundary of acceptable; but, as evident here, "none" is no longer permissible in that set.
