Most other companies can be selective in what they host / stream. YouTube will host/stream anything users upload and that's actually quite insane. Current statistics say that YouTubers upload 30.000 hours of video.. per hour.
Aside from the streaming/processing, only the disk space that would need is already frightening. Most of those videos will never be seen, and no ads will be played on them. The setup needed for this is massively more impressive to me than services like Netflix.
Do you perhaps have a source for those profit margins? I really wonder if they're already running break even.
Interestingly I can agree on the grossness of it, only when "the mood"™ arises a kind of nasty turns into attractively naughty. It's a strange alteration. Like the new texture of a food you might find somewhat repulsive at first suddenly becomes highly addictive or desirable when you give in to it. The sleazy feeling of wanting to keep popping bubble wrap plastic without stopping.
This differs based on time, context (persons) and general mood.
I wonder if at a base level we have kind of the same attitude, but the hormonal alteration or lack thereof is what creates the differences and clouds my mind while yours stay sharp.
