You may already know this, but there's a decentralized proxy service for watching youtube videos called invidious. Find a reliable instance from instances.invidio.us and enjoy a cleaner youtube experience without all the tracking stuff. It even works without javascript and doesn't show frequent recaptcha pages while on tor.
Go to the preferences page and make sure the proxy video option is enabled. This will make sure you never connects to google for video streams. Note that enabling proxy may slow down your network, so choose a reliable instance.
Peertube is my recommended alternative for leaving youtube behind. Use sepiasearch.org for searching videos on peertube vidiverse.
Peertube's main highlight is that its federated (like lemmy). Meaning its not a single website, but rather a network of interconnected websites. It also has features like peer-to-peer streaming, reducing load on servers. sepiasearch.org allows you to search globally on this vidiverse.
