The worst part of it was when it was time-based advertising content. We were forced to watch commercials for "coming soon" content that was going through a marketing cycle but often turned out to be garbage.

So before you even get to the launch menu for this specific movie you selected, you're subjected to a trailer for a 20 year old movie with a 24% on rotten tomatoes. And an advertisement for a pizza restaurant.

Even allowing for exaggeration, some DVDs had a horrifying amount of non-skippable content.

it's still not okay on a bluray

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

A studio logo and some piracy warning and ads for other movies and opening animations and...
