The models are not what is being discussed here, it is the harnesses. That is, Claude Code, Codex, and what you use, GitHub Copilot. I suspect there would have to be strong reasons for your Fortune 500 company to switch away from Copilot.
Similarly, I have made no ground in arguing to try to get Codex at the company I work for, which got Claude Code a year ago and sees no reason to go through the whole process of setting up any alternatives when Claude Code already works and is at the frontier.
claude code is free to use, you can use claude code with any non-anthropic model, so harness stickiness doesn't benefit the AI labs at all.
Claude Code is closed source software that has had quite a few documented bugs with degradation when using non-Anthropic models, FWIW, I would not suggest using it.
