Well, the alternative and more charitable interpretation would be that you are more likely to build a better product in the stack you know well and enjoy.

I think when you get more concrete about what the statement is talking about, it becomes very hard to assert that they mean something else.

Like if you are skilled with, say, Ruby on Rails, you probably should just use that for your v1.0. The hypothetical better stack is often just a myth we tell ourselves as software engineers because we like to think that tech is everything when it's the product + launching that's everything.
