Is it ethical for companies to commoditize open source projects (without giving back!) ?<p>Is it the case that Sagemaker Notebooks (https://docs.aws.amazon.com/sagemaker/latest/dg/gs-setup-working-env.html) are just commoditzed Jupyter?<p>As far as I know, Jupyter went through a very rough process evolving from ipython notebooks essentially /w giant amount of effort from Fernando Perez and community. From what I can see (Amazon) now decided to commercialize essentially the end effort of a decade of work without ever really contributing back (e.g. http://jupyter.org/about) to the community.<p>While this may be legal (re: licenses), is this ethical?<p>vs the various other consulting companies built around an open source offering (e.g. Red Hat) or that also contribute back to core dev while selling an offering (e.g. Cloudera)
