I don't think the vast majority of users use browser plugins at all. Vodoo or not, the barrier is high enough that it's not a common practice. Certainly not trivial. See the next section; I do think there's a genuine blind spot among tech literate people.

It's kinda like if cars shocked you every time you touched the steering wheel. Car enthusiasts of course know how to pop the hood and remove the shock module, but most drivers aren't car enthusiasts. So when people have a conversation about cars, it needs to start with 'yeah shock wheels kinda suck' because that's what cars are to drivers, even if you have a workaround. If leaving the shock module in as a reminder is what it takes, so be it.
