Several patterns emerged out of cloud services that enable cloud services to work better - namely event driven architectures, various cost savings strategies, HA/DR postures, etc - that cannot be applied to non-cloud architectures or even monoliths. If your team wants these patterns, you need to go cloud. Said differently: if they want experience in AWS, that's a proxy for wanting to learn these other techniques. Moreover, this tweet is the rant of a single person that apparently doesn't care for AWS.
