He's also wrong about the definition of legitimate ads.
The creators are encouraged to have in-video adverts (god I hate that shit more than anything, actually), but some people get monetization from the commercials generated onto their videos.
Commercials that Adblock blocks.
"non-subscription"
If it's playing ads through Adblock, I don't know what to tell you. If I'm not using a paid account, wherein ads would be removed anyway, its always told me to turn Adblock off
While some of it is grey-area, not all. Last I checked, Hulu and non-subscription Crunchyroll don't run well with Adblock.
I mean.... Hulu doesn't run well in general, but worsened with Adblock.
I only see ads on Youtube when using non-Adblocked computers.
Most streaming websites request Adblock to be off so that their ads will play.
Seems like you're doing something with these programs most of us aren't.
I was about to ask which Shiro, and then I realized both Shiros I can think of are complete garbage, so there's no saving you unless it's a different one.
