Not listening to the ads is so far from stealing, I am almost not sure if you're serious. It's my right to decide whether to rewind a minute, to lower the volume, to skip a whole boring episode etc'. It's also my right to process the content with an app that modifies it, for my own use.

It's not the act of not listening to them that's stealing, it's the act of algorithmically excising them that's stealing, especially (but not exclusively) if there is a premium option available.

For example, watching non-premium crunchyroll with an ad-blocker enabled is dishonest, IMO.
