Well, now organizations like Wikimedia are going to have to drop Elasticsearch everywhere despite it powering wikipedia article search and more. So congrats on both missing the GP’s point and also failing to see how this license change would shrink Elastic’s usage / market anyway
They don't need to drop. They're not providing Elasticsearch and Kibana as a paid service to others. You can just read the FAQ: https://www.elastic.co/pricing/faq/licensing
Using Elasticsearch and Kibana is still free, unless you're selling them as a service like AWS Elasticsearch does.
