In fairness to SpaceX, Falcon Heavy's long delays weren't a result of mismanagement or false claims. The delays were due to Heavy turning out to be largely unnecessary for routine operations and development being put on the back burner. Falcon 9's capabilities (particularly in the engines) were improved to the point where it could handle missions once thought to require Heavy. Those same continual improvements meant that it was a more efficient use of engineers' time to wait for the more-or-less final Falcon 9 design before starting serious work on Heavy.

But I do share skepticism on Blue Origin. It's hard to develop rockets in total secrecy. If New Glenn was anywhere close to flying, even in an expendable test configuration, we'd at least know that much even if they chose to keep the details confidential.
