by the way, does it make a difference if it's closed by lender, or closed by consumer?
It doesn't matter as long as it is good standing. You already took hard pull. If I were you, I would keep it. They might not do it to you. It is YMMV thing. It is a good card for travelling rewards. I have two cards and they haven't done anything.
By the way, any creditor might close if they see something they don't like.
