YouTube still pays creators pretty high comparatively (55% of ad revenue according to https://www.businessinsider.com/how-much-influencers-get-paid-on-instagram-tiktok-youtube). You are simply getting a service (hosted, searchable, collection of the largest collection of web videos in an extremely nice interface) that costs money even outside of the creator’s cost. For creators they are allowing that 45% cut of ad revenue to get access to the YouTube audience, paid hosting that simply works, nice creator tools, etc.
You can state that it’s a valueless thing that anyone could replicate, but the evidence is that there aren’t many alternatives that do better. Today we do have things like PeerTube (which I think all creators should consider selfhosting with ads/subscriptions and federating the free stuff after a delay) and joining creator owned video services like Nebula (which could be made even better with federation). Unfortunately, with both you run into the discoverability problem, something creators and their audiences are paying to solve when you are hosting on YouTube.
I’d take your argument further back on the sourcing of getting content to you - why should you pay for internet service when it’s the content of the videos you watch not the wires that deliver it that have value? If you hacked around your neighbors WIFI to get some free network access, you could zero-cost get something you might not necessarily want to budget for, and you get quite a nice service out of it. Why shouldn’t that be okay when you still Patreon the creators of your videos given your reasoning about YouTube providing no value?
Great points!
