Similar things happened with USA's actions on Silk Road, KAT, with Kim Dotcom, and I'm sure many other legal situations I'm not aware of.
EU is seemingly extending logical contact to be equivalent to entry to a jurisdiction as USA appear to have established is desirable as a facet of inter-national application of law in the internet age.
I much prefer the extension of jurisdiction in protection of member states citizens rights than in the service of media conglomerates.
In no way shape or form does US law has a direct mandate outside of the US.
All the examples you've given were those of actions performed through established legal channels to which all parties had and have a saying in.
Extra-territorial application of the GDPR under existing frameworks (or the lack thereof) is tyrannical because you apply it to people that have had no saying in the establishment of the regulation and have no control over the interpretation and or the enforcement of it.
If you would push for this the only thing that would happen is that companies would stop accepting orders from the EU.
If this is going to be the definition expect a lot of store fronts to be closed to EU residents following May 25th or more likely the first time this precedence will be set in court.
