TI processors tend to have weird misbehaviors and the support is far worse than competitors like NXP. Plus, their driver quality is usually low, and actually using driver or bsp code is difficult in a consistent, automatic way. You want to regularly upgrade drivers/bsps that you're carrying a couple dozen unofficial patches on top of. The tooling available forces you to do that semi-manually, which also means people make mistakes and introduce unnecessary regressions.

Even when their stuff works, I've had too many instances where the support resolution was "ensure you're doing everything in this 1,500 item checklist" (not exaggerating).
