Easier said than done… if you are a YouTube creator, are you supposed to set up your own video hosting to compete? And how many of your viewers will move over to watch your stuff there? This advice probably works for blogs and mailing lists but isn’t really actionable for other content.

Your YouTube example is exactly what gave rise to Nebula.tv—creators banded together to create an alternative that would backstop them against YouTube's dominance.

All the 1000 of your mailing list subscribers? Or maybe 10k.
You start needing alternatives when you're already established and have a following. With this comes large enoug influence and thus the ability / risk to step on some big toes, including Google's.
