Are you talking about Netflix? I mean they are really cheap. I dunno why someone would pay per episode instead of having a subscription.
Netflix is just one of the many. Every streaming service has its own selection of series/movies/documentaries that it offers, which would require people to have numerous paid (monthly) subscriptions just to watch what they are interested in. This also applies to porn sites where people mostly look for specific scenes and photo sets of their favorite models.
I mean 9 bucks are less than the transaction fees which bitcoin had during the Bullrun. But I would love to see Netflix accept cryptos.
Most people here don't complain about fees because they generate most of what they have through campaigns, tasks, etc. People putting fiat on the table felt the pain of the high on-chain fees last year, so it really matters. Another thing is that it just doesn't make sense to pay $9 for something that also requires a $9 (or higher) on-chain fee, which is why LN is so important.
