It kind of is. YouTube has decades of history. Unfathomable amounts of video. No indie platform will ever come close to hosting more than a fraction of a percent of YouTube’s library and be as accessible and as fast. It would cost an unbelievable amount of money in servers and maintenance let alone moderation. The problem is this is a service, like many others that exist today, that does not bring in more money than it costs. YouTube exists because it’s a branch on a megacorporation tree, but even Google will eventually need to find a way to make it profitable. It is impossible to fund this for free or anywhere close to free.
