So at the very least you have no right to make assumptions about them then. I merely provided one provable example that contradicts your generalization.

There are a fair number of other replies in the thread saying they, too, don't see widespread eSIM adoption when traveling abroad. So it was an educated assumption, to be fair. I only speak authoritatively on the US, because 1. I live here, and 2. I've been doing a metric ton of research into carriers and MVNOs as I'm looking to switch very soon.

Actually the EU consists of an alliance of 27 historic European countries.

Noted, and corrected.

I agree and hence welcome a device manufacturer advocating for change, with a Two year transition period and for an already launched and tried technology nonetheless.

In this case, I'd honestly prefer to keep physical SIMs around. eSIMs are super convenient yes, but...well, let me use myself as an example: I get some service through a Verizon MVNO. For whatever reason, Verizon seems has a restriction on MVNOs they don't own where they're not allowed to activate 5G devices. So when I tried to activate service on my iPhone 13? Denied. It's a 5G phone and "incompatible".

I was able to sidestep it by putting the SIM into an older phone, activating service there, and then slipping the SIM back into my 13. Works great now, Verizon can sod right off.

In an ideal world, we wouldn't have these problems, but with eSIM, I can imagine that the MVNO's site would catch the IMEI just like it did when I tried to activate and actively stop me from moving my service over.

If carriers weren't such dicks, I'd love eSIM. I mean, I already like it, but yeah. But as it stands now, I feel like ceding more control to the carriers like this is a bad move. But that's probably more of an American problem than anything because we love our deregulation, it seems.
