Spacelift co-founder here - please don’t panic. We will make sure you can continue to use Spacelift :)
I don't know the details of BSL, but can HashiCorp now require compensation/$$$ from Spacelift, Scalr, Env0, etc? In that case, these products can be forced to offer similar pricing as Terraform Cloud.
In other words: if you hard fork now, you don't need to pay.
