For the record, here's another "difference between what Dave Filoni and George Lucas said" post (for more, check here). Real quick.
When it comes to Dooku's motivations, George had this to say:
"[The scene with Obi-Wan and Dooku] allows you to kinda have some sympathy for Dooku in that he carries the sympathies of most of the Jedi which is that the Senate is corrupt and is incapable of carrying out any meaningful actions because they argue about everything all the time.”
Dooku carries the sympathies of *MOST* 📢 of the Jedi.
To be clear, he's not the only Jedi who sees things for what they are, who sees the Senate is corrupt and is incapable of carrying out any meaningful action because a majority of them are now self-serving assholes. MOST of the Jedi see this and acknowledge this.
It's not that the Jedi don't see it and thus don't do anything about it. They see it, but they're not allowed to do anything about it.
"Even the Jedi are [present when Palpatine gets emergency powers]. But the Jedi aren't really allowed to be involved in the political process. They're there, but they can't suddenly step up and say, "No, no. You can't do that." They have to let the political process go."
Which is why they do their best to help everyone within the confines of their mandate.
Whereas the narrative of 'Tales of the Jedi' phrases it as-- what was the line? Oh, right.
"The Jedi BLINDLY serve a corrupt Senate that fails the Republic it represents."
And there you have it. That's the difference.
Filoni, through 'Tales of the Jedi', frames Dooku's perspective on the Senate's corruption as him and Qui-Gon being the only ones ahead of the curb when every other Jedi is blind to it.
Lucas literally says it's most of the Jedi Order who know this sad truth but they're not allowed to interfere. So they do the best they can with their hands tied.
