It’s guaranteed to be worse: TV episodes are completely structured around whether the creators expect ads, and where in the runtime the ad will be (so they can resolve or tease a plot point before them).

The addition of ads, or having more ad breaks than the original transmitter of a show had, will break the structure.

And then of course there’s the ‘Spotify question’: are these ads genuinely supporting a subscription, or are they there to annoy you into paying for one by disrupting the flow of an episode as much as possible?
