If 51% of miners could change anything everyone would be spinning up Alpine Virtual Machines with minuscule hash power. You fundamentally misunderstand how blockchain works.

Your "we" in the second example is the majority of network users - any network where that isn't true is not decentralized.

You do not know what you are talking about. The fact that grifters often don't know what they are talking about and use that to whip up positive spin on blockchain tech does not give you any good excuse to do the opposite - you are both morons.
