I think 'kill' is appropriate here. They shut down access to his company's account along with all running infrastructure and after escalating multiple times, their final official response (after 30hrs of silence) was that his company was permanently denied access to the account (DO calls it 'account termination' in their postmortem). The first tweet of the thread that went viral was 'How Digital Ocean just killed our company' [https://twitter.com/w3Nicolas/status/1134529316904153089].

I don't want to spent too much time dumping on them since they clearly know how badly this situation was handled, but this is an example of terrible automated protection leading to a company that's not enterprise-ready. As you say, AWS probably doesn't publicly promise not to terminate your account, but this would never happen because they understand that availability and security matter more than anything else when running B2B infrastructure.
