@makegeneve They can because they require contributors to sign Contributor License Agreements which signs over the individual developers copyright to Hashicorp.
Most developers are okay with that because they assume companies will switch from one open source license to another (say MPL came out with an upgrade). Hashicorp took advantage of that good will to steal and relicense the work. While legal, it's certainly not ethical.
