Amazon are the masters of theivery. The hypocrisy is not going unnoticed. Amazon contributed nothing of value to open source, then they basically stole the hard work of others and again contributed nothing back and now they're going so far as to preach about open source. Please. The sad part is, users won't care and customers won't care because at the end of the day ease of use wins. Elastic are taking drastic measures which will in the short term impact then but hopefully in the long term everyone will give more thought to what licenses they choose. Open source is no longer just about the freedom of choice but now a marketing and commercial strategy for big tech. Just keep that in mind if you ever want to build something of value in the open.
