Huh, I didn't like it because IMO, it "redeemed" Rick too much in the episode. The Rick and Morty episode was about how even though Rick was powerful, he was still a jerk, and in his jerkiness he did destroy something flawed, but good (the Vindicators). Here we see that the Vindicators actually were phonies, genocidal monsters, and horrible people. Rick destroying them is actually a good thing. Which is just justification for Rick being such an asshole in the Vindicators episode.

These episodes didn't add to the story, they took something away from the story.
