In my case it's more that learning Heroku would take me longer than using what I already know well, Kubernetes on AWS. So it wouldn't make sense for me to use Heroku (a tool I don't have much experience with), and pay more. In terms of use of my time, to be honest I currently spend way more time sending emails, updating docs, and on "marketing" than on devops :)
