Fraud vector. It's very easy to turn compute into dollars if the compute is free or stolen. Cloud compute is very cost ineffective for something like coin mining, so any actual legitimate miners on any chain are going to just run everything in-house anyway. In the end, that means the people left in that pool predominantly fall into two groups: A) people using stolen credit cards B) accounts that had hacked credentials or leaked API keys running rampant. Whatever heuristics cloud providers tend to use to discover and "remediate" such behavior is a totally different thing (e.g. obliterating an established account when an API key might have gotten leaked and a few GPUs let loose is a little overboard), but if I was offering a similar compute service, and its sole purpose wasn't just coin mining, I'd almost certainly ban it as well for similar reasons.
