What the hell does "Docker's new direction to go back to its roots and focus on developer tooling" even mean? Docker is developer tooling, that's the whole product. That's not "going back to your roots" that's just doing your damn job.
Heck within the first few weeks of dockerizing our system at a startup (c. 2015), they introduced a backward-incompatible change to docker-compose that we only found when onboarding new employees -- the exact thing it's supposed to be for!
"How should we improve user experience? I know! Let's ruin user experience by forcing users to signup for an account they don't actually need! Brilliant!"
As tempting as it is to weigh in publicly on such matters, the best way for a developer to get results is often to say little in public and try to resolve the issue behind the scenes (as was apparently done here).
