It’s not “blindly” when you’re purchasing something based on a feature set advertised by the manufacturer. It’s quite reasonable for a customer to assume that those features will be in place and working as advertised when they receive it.
If you bought a new car and found that one of the wheels didn’t turn smoothly or the brakes failed 10% of the time you’d quite rightly be furious as you expect something to perform it’s basic functions as advertised. You would expect the manufacturer to have thoroughly testesd it before it was released, not to wait for the first batch of drivers to start crashing before you worried about fixing the brakes.
