I think there's substantial value in replacing expensive system components with free alternatives. Things like FusionAuth / https://fusionauth.io/ for user identity (full disclosure, I'm an employee) and Pentaho Kettle https://github.com/pentaho/pentaho-kettle for ETL and data transformations can help.
It is important to recognize the value of developer time too, though. There's a cost in dev time for setting up a "free" project.
That's why I think that any open source project that gets too popular will have to have a cloud vendor strategy, otherwise they'll get done to them what AWS did to Elastic Search.
I also thought it was interesting that the author mentioned support for the various application libraries. I know that there have been several "tip" type applications (gittip, gitcoin.co) that try to align incentives and allow open source developers to make a living.
