Right now, I'm the guy looking at the butterfly thinking "Is this an Andor meme?", rather than just enjoying the movie or whatever. But Nimona is really good btw (and bonus points: it has Riz Ahmed [Bodhi] in it!)

I never watched the trailers before the show, but they're very good. The music for the teaser, especially, really evokes the show.

Tansy Gardam (from the Going Rogue podcast) has said it's Tony Gilroy, but I think it's more likely to be his brother. Unsurprisingly, they sound alike, and John has spoke about providing temp dialogue from his editing station.
So I think that scene is just one where they didn't bother to replace his voice with an actor's.

The credits last episode I saw has writer's names separated by the word 'and' (rather than an '&' to show they were working together), and a line for "Director of Photography for Additional Photography".

In other words, they had to do re-writes and re-shoots for a 30 minute episode of television. Given that, it's not surprising that the end result hasn't lived up to the promise.

Notes:
This insert shot for the reshoot of Cassian's "Spies, Assassins, Saboteurs" speech is merged with Principal Photography of the scene, with the gang appearing in the background, and then shots of Jynn used to mask the transition.
It must have created a lot of work for costumers, make-up artists, hairstylists, etc, getting 20 dudes looking exactly the same as they did a few months ago. Expensive way to make a movie!
K2 is also at the back of the group, but he wasn't mo-capped by Alan Tudyk. Likewise, they used a stunt performer for K2's "rescue" of Jynn on Wobani. He was present to film his death, though.
None of the Additional Photography was shot on the large, purpose-built sets they originally built. This scene gets noticeably livelier at the end, back to using footage from when the cast were on the set for Yavin IV.

Transcribed from an old, mostly in-French, interview with Gareth Edwards:

We felt we needed to have some characters in the film that represented a belief in the force, because there's no Jedi in our movie - it was in an era when they'd all been made extinct, in theory. And so, to try and get inspiration I'd watch the things that inspired George Lucas, which was the original Akira Kurosawa film The Hidden Fortress and in that film there are two asian characters that bicker and squabble a lot, and they became, eventually, R2-D2 and C-3PO in the final movie. So we just rewound time and didn't make them droids, and kept them as two asian characters fighting. They were like the yin-yang of our film - the Belief and the Not-Belief, like War and Peace, which became Baze and Chirrut.
