Google must be mad Tim is likely doing a show with Joe soon. So far listening to the stream that got pulled I don't hear much there unless they got pissy about calling out the same old media lies.
Since Google won't comment you can just assume it's because they're evil fuckers in general that don't want any truth to get out. YouTube has pulled channels for reading right off the CDC website before, so there you go.
Remember Google works with the Chinese military on AI, has a domestic spy/propaganda/censorship program (Jigsaw), and developed a 'great firewall' (Dragonfly). Dragonfly leftovers are likely being used now in the US. Stomping on free speech is just the ground floor.
