@YHBF I don't think the two scenarios are comparable. Youtube is not too big to fail per say, it can fail pretty hard and take all the content creators down with it. What I;m saying is there is no "next site" that's going to arise while Youtube is alive that's going to snatch away all the Youtubers and kill Youtube. This isn't the same as a social media site killing another, thousands of people use Youtube to make a living, and most people who go to Youtube go for those people.
Moving their livelihood to a new site is a HUGE risk that has a 99% chance of failure. Think about it. In order for another site to completely replace Youtube, it would have to take most of Youtubers content creators, which would mean thousands of people uprooting their ability to pay their bills and eat, and move it to another site with absolutely no guarantee that enough of their fanbase will follow, that the new site's ads will rake in enough money, that the new sites guidelines will allow them, that the new site won't turn into another Youtube anyway, or that the site won't get bought or go bankrupt (remember, the Youtube model is not profitable and is only afloat because Google can absorb the cost) that the site will be popular enough to keep enough new fans being made to replace leaving fans, or that advertisers don't so the same shit there as well.
Youtube isn't like other websites. Youtube's death isn't dependent on the userbase staying, it's dependent on the people whose livelihoods depend on it leaving. The only way that will happen is if Youtube straight kills most people's ability to live off of them, and that will just kill Youtube, there's no guarantee that something will replace it if Youtube straight up dies, or if most content creators just go to Patreon for money and stay on Youtube because that's were their thousands of videos are.
