I have lawyers make up terms and conditions that are really great for me, but which might cause real problems in some specific jurisdiction. Do I serve two terms and conditions or just one and hope I don't get in trouble.
I think once I'm big enough and have expensive lawyers might as well craft the terms appropriate to areas.
But now gets tricky in area A I can say "We have the right to change these terms and conditions unilaterally at any time we wish and you will be bound by the new conditions"
Now someone in area A moves to area B where terms and conditions are not as great for my company, and where you are not allowed to change terms and conditions unilaterally. Maybe I change terms for A to B immediately when they move to B so I don't get problems. But now they move out of B back to A, I probably have to ask them to agree to A conditions again.
Anyway, it is funny wondering just how nefarious these companies are with the terms and conditions.
