But that was the whole point. You never had any visibility into their roadmap.
You only evet had visibility into a daydream that changed. What good is, no scratch that, there is no good in knowing something that you only think you know. It's negative value. It's worse than knowing nothing at all. It doesn't matter how much you want to know, and how good it feels to have that want pacified.
Similarly, this is also why even if someone does publish a road map, you should ignore it and only deal with whatever exists as it exists right now. Make all decisions, including looking ahead, based on nothing but the current state.
By that same logic, if somebody tells me they will pick me up on the way to a movie, I should go there on my own because they aren’t here already. I should walk to the movies, because my car is not currently running and whether or not it starts is in the future.
There’s such a thing as trust. Tools, people, and groups that have shown themselves to be trustworthy may continue to be trusted. It is also reasonable to point out these shifts, so that others know when announcements should no longer be trusted.
