I sympathize a lot with the licensing story of Caddy. /u/mholt has been a very active maintainer and participant in the larger Go community and has every right to create a commercial side to the project and receive compensation for their work.

But licensing is hard. AWS abused the leniency of Elasticsearch's original OSS license, so now the industry is set back 10 years with new entrants trying to find the balance between inviting community participation and getting gob smacked by big corporate interests.

Im not saying Elastic.co is an angel but its a lesson OSS projects have to take to heart, unfortunately. Thanks Amazon.
