Scope creep by developers and front line management is the normal kind of scope creep that is to be avoided.
Scope creep by upper management can be an informed pivot. (And frontline scope creep requests could be pushed up to be blessed as a worthwhile business decision... or not)
The difference is that all the considerations relating to slipping the schedule can be traded off (at least in principle). I'm sure WayTools is painfully aware of the impact of their choices regarding the scope creep.
I'm not so happy about that decision as well (not shipping the old firmware). From my perspective, it was the wrong one. However, they made a business decision with their money behind it (and way more info than I have). Hopefully, it will be the right decision for them.
I do feel like they are selling a different product than the one that was originally offered They didn't like me calling what I thought I was buying clunky, but at the time, they acknowledged that it was a first release and it seemed at that first product party that people's reactions were that it had more promise than delivery. I bought it in April, so thought I was sort of buying into the first release beta test program. As everyone else not in the TREG, I'm bummed that I'm not.
However, I'm still eagerly waiting for the general release and hope your GR prediction is at least a couple of months pessimistic.
@waytools If you take one of your models from the March 2015 event and switch it with your current model for an hour, I'd really like to know how you would describe the earlier model.
