[Star Wars] Why didn't Yoda and other surviving Jedi join the Rebellion after Order 66?
gpt
At first there really wasn't a Rebellion, it took a few years for it to gain momentum. And by then most Jedi had been hunted down. As for those remaining, the ones that didn't join had personal reason. Yoda seemed depressed and was in self-imposed exile for his self-perceived failures. Kenobi felt that it was his duty to protect Luke.

But some Jedi did help the Rebellion. Ahsoka Tano helped found the Rebellion and Kanan Jarrus eventually would join as well. Though for spoiler reasons they wouldn't be around to help Luke.
