I disagree.

I’ve hosted on AWS for ages. They don’t do this. We didn’t pay the bill for two months once because the owner of the card left. No problems. This was a small spender outfit. They could have thrown us on the street as we were a rounding error. Now we’re a big spender and we still forgot to pay them sometimes (sorry Bezos)

But some of your point is worth considering. Design for portability should the worst happen (you are cut off due to geopolitics or other problems) or somewhere else turns out to be a better deal. Stick to IaaS and portable services only.

For the moment I trust AWS though.
