[$] Elastic promises "open"—delivers proprietary
Open-source software is famously able to be used by anyone for any purpose;
those are some of the keystones of the open
source definition.
But some companies that run open-source projects are increasingly unhappy
that others are reaping some of the profits from those projects.
That has led to various
efforts of "license reform" meant to try to capture those profits. So
far, those efforts have just led to non-open-source licenses, thus projects
that are no longer open source. We are seeing
that play out yet again with Elastic's mid-January announcement that
it was changing the license on some of its projects.
