@szbalint Fair point (and I addressed that late in the tootstorm). I think the structural problems with PSTN are too great, and that the defections will hit too soon for either extant US telcos to recover or continue.
I also suspect that the EU and elsewhere may simply be lagging the US experience by a few years, though we should find out on that point fairly shortly. The same underlying switching and signalling limitations as apply to the US also apply to Europe, and bad actors will bad act.
Exclusive or something
