Not really, the show was a massive success, and he took co-control of the show after they left, giving us Michelle Paradise's character driven, Gene Roddenberry style ideals in her reign.
Bryan Fuller was fired as showrunner for Season 1 before a single shot was even filmed, though he had already committed the show to a lot of expensive mistakes, including tons wasted on pre-production of expensive props/sets and on-location shooting in Jordan for a throwaway scene that could have been filmed in California. They apparently pulped nearly all of Fuller's original vision past the first two episodes, with the new showrunners (his former assistants) being given control because they were the only ones left standing with any pull in the writer's room.
And then it happened again in Season 2, with those former assistants (Berg and Harberts) fired - this time in the middle of Season 2 being filmed, which led to a production pause, reshoots, and (probably) an entirely new plot arc involving Control being constructed to try and salvage the first 5-6 episodes.
I honestly can't think of too many other examples out there where a studio fires three showrunners in two years, though part of that is undoubtedly because in most other cases, they just would have pulped the show and written it off as a tax loss. But CBS was committed to resurrecting Trek, so Kurtzman kept looking around until he found Michelle Paradise in the writer's room, handing the keys to her by the end of Season 2.
Picard's show runners were also successful, Chabon is a great writer and moved on to develop a story for his own novel because Picard of thst. Regardless if Picard season 3 is lesser to me than most, it's considered a success too. I enjoyed most of season 2 as well, but having Matalas/Akiva/Chabon basically do a third of the show each hurt the coherency somewhat.
I liked a lot of what Chabon was trying in Season 1, and I cannot begrudge him for wanting to move on for the adaptation of his own works to screen. That said, for whatever reason, the show ended up with three showrunners telling starkly different, largely standalone stories in each season, which not only didn't follow one another, but actively undermined what came previously.
To give just one example, Season 2 was about three things - Jean Luc becoming open to a relationship with Laris, the death of Q, and the introduction of a non-antagonistic Borg. Every single one of those choices was undermined by the choices that Matalas made in Season 3. Picard isn't with Laris, Q appears in the end credits, and the Borg Queen is back, baby!
