The problem with the debates is that it's difficult to discern when someone is debating with real authority on the subject versus appealing to authority. A lot of engineers will say things "We need to use X, because Google, Facebook, etc use X". All the while ignoring the fact that Google and Facebook deal with massive scale, have tremendous resources to bear, and hardly get penalized by their customers when things break. The tech is only one small part of a much larger puzzle. It's often easier to suppress such debates than engage in them, especially in the early days when you don't have the luxury of time. I'm not saying it's always the right thing to do, but it's often not the wrong thing to do for a team to continue shipping at a regular pace.
