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…
I might be in a bubble of course, but from what I've seen, I've been positively surprised by the uptake of OpenTofu so far!
I do also expect OpenTofu 1.7 to be more interesting for people to migrate to, as it'll include a bunch of OpenTofu-exclusives.
