My job is managing infrastructure, services and products for large corporations in the cloud. It is managed hosting, and SaaS/PaaS, and yes, there are plenty of providers who have alternatives that we regularly use, in addition to being able to build our own with mostly open source tools. It's part of my job to find alternatives so we don't get into a jam when the one solution we use becomes unusable. The most "cutting edge" things I remember announced at re:Invent 2019 were machine learning and AI stuff, but it was all stuff integrating with existing 3rd-party services and products. They know you want to be able to work with somebody else's tool, and they want to make it easier for you to spend money using that tool on their systems. The bulk of AWS's income is still EC2 (and data transfer); the rest is window dressing to keep you from looking elsewhere.
