Vagrant is going proprietary

https://www.hashicorp.com/blog/hashicorp-adopts-business-source-license

HashiCorp decided to switch all its products, including Vagrant, to a proprietary license ("Business Source License"). The last version under MPL will be Vagrant 2.3.7, which will get security updates till 12/31/2023.

Should we switch from Vagrant to something else? Or just wait for a fork that will continue development under a free license?
