the approach that caddy has taken appears to be a bit of good cop / bad cop. they're maintaining, at least for now, the apache license but they're also using trademark threats to prevent forks (i believe in violation of the github TOS)
the approach that i'm hoping to take is quite different. i'm interested in any feedback (my software is a database engine that in some ways is more convenient than existing dbms for java developers, but similar to caddy in that many good alternatives exist and are free)

- you can freely copy, modify and distribute the software
- non-production use is free, as is production use on up to 10 cores
- prices are predictable and non-discriminatory
how would you feel about using software (in the infrastructure space) under this license ?
