Generally my stance with these forks born from community drama is "wait and see." Sometimes the fork will gain traction and become the de facto "true" version (see Hudson -> Jenkins). Sometimes the fork will flop and people will largely stick to the original despite whatever caused the schism (see Terraform -> OpenTofu). Many of these recent forks are being done because people won't want AWS/GCP/Azure to slap a UI on…
The hyperscalers weren't selling Terraform though, Hashicorp was losing to Terragrunt, Spacelift et al, who had decent to good offerings. I'd say Elasticsearch is still the comparison to make here for a product that clouds just resold, then again, Redis the company didn't build Redis the software and their latest marketing smells more of VC hawkery than any reasonable pitch
Would love some data in support of this statement. Not saying you're wrong necessarily, just it feels like a perception vs. reality comment potentially.
