The answer is... Because that what the toys were like and the cartoon models had to reflect that.
In other words, "To sell toys."

It's commonly theorized that Waspinator, Dinobot, and Rhinox were shielded from the quantum surge since they were each inside a CR Chamber (or CR Tank in Waspinator's case) at the time. Meanwhile, Tigatron, Airazor, Blackarachnia, and Inferno (all born on Earth from stasis pods instead of coming from Cybertron already up and active) were mysteriously unaffected.
But the real reason that only some were Transmetalized and some weren't was because Mainframe's budget only afforded them so few new models per season. In just three episodes, we got new models for Cheetor, Rattrap, Megatron, Tarantulas, and Optimus, plus two newcomer models for Silverbolt and Quickstrike. That's seven new models that needed to be made right out of the gate for season 2, and half the total main-character models that season 1 ended up having. And an eighth one was not far behind in the arrival of Rampage just five episodes later.
It's no wonder they had to kill off Terrosaur and Scorponok in the first episode, remove Tigatron and Airazor from the show (first by sending them off on a journey in the second episode and then bringing them back midway through the season just to have them abducted by the aliens and never heard from again until near the end of season 3), and then kill off Dinobot right after Rampage was added to the cast. Mainframe had to make room for all the new character models in order to stick to the tight budget for CGI television at the time.
Though, they must have either gotten a bigger budget or figured out how to balance it better for season 3 since they were able to add Depth Charge, Transmetal 2 Dinobot, and Tigerhawk to the model count without needing to kill off any other main characters before the series finale, on top of creating even newer models for Optimal Optimus, Cheetor, Blackarachnia, and Megatron, for a total of seven more new models for that season.
