I see your point. Thank you.

I think most non legally inclined people (like me) would say CBP yanked my GC.

Your point being that - nope, they just enforced the law.

Right?

Yes. People are generally familiar with rights that can lapse if eligibility is not maintained - consider the right to vote in state elections, which you lose if you fail to maintain residency in that state. Nobody yanked your state voter registration or your eligibility for in-state tuition, you abandoned it.
