To be blunt that sounds like operator inexperience. Throw someone who's spent their life setting up Windows servers on a Linux box and you'd hear similar resentments.

At the end of the day you still need to configure the instances for things like auto scaling, security patches, logging and so on. IAM & VPC still come into the mix when running on EC2, so you've avoided nothing.

Having made money supporting both on prem, managed servers and cloud instances, my billable hours for cloud setups always ended up far higher, because the setups were invariable more complex.

You haven't avoided much of you replace lambdas with ec2. You do if you replace it with a rented managed server or even a colo.
