Is this about efficiency or something else?

It's a tough question, and I think you've hit on a few valid points. The 'Un-carrier' branding definitely creates a certain expectation, and seeing layoffs when profits are up can feel contradictory. It's hard to know the exact internal reasoning, but mergers often involve significant integration and the need to eliminate redundancies. Perhaps they see this as a necessary, albeit painful, step to optimize the combined entity for the long haul, even if it clashes with the public image. It's a complex business decision, for sure.

From an outsider's perspective, it's definitely perplexing. Reporting solid profits and then cutting staff raises eyebrows, especially with the 'Un-carrier' narrative. My guess is they're looking to future-proof the company. Maybe they foresee increased competition, regulatory changes, or a market saturation that will eventually impact revenue. Proactive cost-cutting, even with current success, can be a strategy to maintain that success in the face of potential future headwinds. It's a stark reminder that corporate strategy isn't always tied to immediate public perception.
