For cloud providers, security is their raison d’etre. On the cloud you can have confidentiality, integrity and availability that was unheard of two decades ago.
No, it's not. Cloud provider's raison d'etre is selling access to compute resources. That confidentiality and integrity are resources they can also sell does mean that they might spend more on those things than would otherwise be expected but if their single and sole purpose was security, they would't be selling networked access to computer systems at all because that is objectively less secure than physical terminal access. But no cloud company that requires their customers to staff a physical presence at a terminal in the data center is going to be as successful as one that allows you to remote into your cloud from anywhere, even though tht is objectively less secure.
