Good luck with a lot of wasted work power because you are sad that "big Corp" can't exploit anymore "small software house". Please, this is ridiculous.
Anyway, I'm sure many others like me are sympathetic to the cause and will support companies like elastic that take this kind of decision. I don't think elastic will miss you.
I work for a very well-known non-profit. You probably visit our site multiple times a week, if not per day. We're going to have to move off of Elasticsearch powering our article search, despite us not offering Elasticsearch as a service or anything remotely comparable, because we believe in running free software in production only.
So, I hope you enjoy taking the holier-than-thou stance. It must be nice up there.
