What even is your point here and in this thread? Acquiring customers and giving them an incentive to stay is a cornerstone of any enterprise.

Saying lambda is bad because of lock-in is like saying their VPC offering is bad because of lock-in, or IAM is bad because of lock-in. It's not a generic component that you can flip between providers, they usually respond to a specific event from an AWS service and nobody really gives a rats about deploying their specific lambda to a cloud they don't use.

So yeah it seems like a real awesome idea to avoid vendor lock in for a small python function that responds to S3 change events from a SQS queue and updates a DynamoDB table with some values.
