> When thinking about a new proposal, it's often safe to assume that Occam's razor is applicable and the reason it is being proposed is that the team proposing it is trying to tackle the use cases the proposal handles.
Ockham's Razor doesn't apply in an adversarial situation.
It is also for when you are comparing two explanations that do an equally good job of explaining empirical data.
"Google is an advertising company and does whatever leads to more profitable advertisements" does a much better job of explaining Google's actions than "Google just wants to build the best possible browser", so it should be preferred even though it is a more complicated explanation.
