It's definitely unfair in a sense. But companies that make over-extrapolated roadmap estimates from not enough evidence systematically outcompete those who don't, because their customers greatly prefer companies who give a date and then try their best to hit it over companies who say they don't know when the product will be ready for X and you'll just have to wait and see.

I get that, and I don't mind giving guidance on roadmaps, it's just the ownership when stuff outside my control goes wrong that bothers me. I shouldn't be responsible for product going in circles on little details with the customer causing req churn, yet I have been held accountable for missing estimates under that exact circumstance.
