The audacity of these AWS folks patronizing elastic about open source despite AWS making millions of dollars off of their open source project just reeks of entitlement. Glad I am never going to use AWS.
Large companies have monetized open source for decades, ever since open source has existed. Red Hat, IBM, Microsoft, Oracle, Amazon..the list is endless. I can't imagine why people will quit the open source movement now because they realize they can't make money from it – that has always been true. Writing FOSS to get rich has always been an oxymoron.
The whole point of "The Cloud" is to profit from F/OSS. And Elastic, Redis, Mongo, and also RedHat have indeed already adapted their licenses or offerings accordingly.
