The person is acting like it's several minutes. It's maybe 20 seconds at most. A studio logo or some piracy warning. You can buy Blu Ray players that let you skip it though. Much worse is minutes of ads throughout what you watch.
you bought the thing, you should be able to use it however you want
and putting ads into a bluray you already bought for a probably not so small price is ridiculous
And if you skip some epilepsy warning then that is your responsibility, same with when you pirated it and get caught.
Also why force me to see anti-piracy propaganda (and that's what it is, nothing else, sometime also legally misinforming) when I already DIDN'T pirate it or a logo I already know from the packaging of the bluray (because if I did pirate it I already would have skipped it).
it's just a ridiculous dictation of behavior in context of a bought physical product
