Same here, very unhappy customer. The new pricing is just nonsense, and now I'm looking for alternatives but migrating out 500 users is not trivial.
Moreover, I'm not too fond of the GitLab approach of replacing all the other typical tools in the DevOps toolchain. I'm happy with Jenkins, artifactory, etc., and I don't understand why I need to pay for something I'm not using or planning to use.
Is anyone in the same situation? :)
