While I can agree with the 4K argument a bit for the hosting is expensive part, I do think it goes way beyond that or long videos. Youtube exists on a scale most don’t even realize. Tens of millions of people upload content every day. We’re talking thousands of hours worth of video every day.
Not to excuse YouTube for a lot of dumb decisions they made, but even on their best day the site just breaks even due to the cost of hosting.
I mainly took it as a joke on all the awful things that happen around Heracles. The DM is stopping the history buff from warning them.
