> My main consideration is for content creators, especially since the ad revenue is passed through to them. Any concern I have about YouTube not being able to sustain itself does not come from a place of caring about Google's livelihood.

The best solution I've found to this is to support content creators directly. Subscribe to their Patreon, Liberapay, GoFundMes, etc. Most YouTubers who sincerely try to make a living from their content already do this. Or just disable adblock for a video or two.
