Okay, but that's not a very useful answer when there are a number of technical reasons why the restriction might exist.

I'm not convinced that the statistical number of people that would regularly move outside their "primary service area", or original owner resale, etc, would drive real issues for them.

Are there reports, for example, that the mass movement of these things into Ukraine is causing significant issues?

Ukraine is somewhat of an exception in that being able to provide any service at all is sufficient. But I do recall that last year, there was an incident of someone driving around with an antenna strapped to their car.

That doesn't stop it being possibly correct? I think it's as valid an answer as any guess that happens to be about technical detail/implementation.

It's just a lazy answer to an earnest question. Anyone reading HN can imagine a "just because they can" argument. I'm asking and hoping someone can help me better understand the technical issues projects like Starlink have.

Alternatively, I'd proffer that it's possibly the correct answer to an earnest question, and a helpful nugget that could easily get lost here in plenty of imagined technical problems, suggested by predominantly technical people used to thinking mainly about that and assuming it's the reason.
