I'm referring to monopoly power - which doesn't mean a singular entity. A good thought exercise to gauge this in this situation specifically is if it's only incidental that they were on AWS. If they were on Azure or GCP I think we can assume the same result would have occured.
Good thing there's still more than AWS, GCP, and Azure in the cloud hosting market. There are dozens if not hundreds of companies willing to rent you computing hardware on the internet. There are dozens if not hundreds of colocations willing to rent you space, power, and network connectivity.
