So if Twitter complied with the demands such that flagged EU-illegal content still remains available to non-EU (e.g. US) visitors, thus not removing anything on the demands of a foreign jurisdiction, in your eyes it would suddenly no longer be a case of "anti-free-speech insanity"?

Cause the whole "they're ordering around an American company" defense falls apart pretty quickly when said American company also operates (read: is accessible from) within EU borders, and in general can be used by citizens of EU member states (independent of their location).

I believe that would be a reasonable solution, but at the same time I would feel bad that the EU has elected people to do such a thing to their people, but ultimately it's not my problem that they got into this state and have a worse version of X.
