$6k/year/seat is not particularly expensive for a dev tool if (very big if) you can measure the value and demonstrate it's worthwhile. That's the missing piece. People look at cheaper options because they don't know if the expensive one is working.

If OpenAI can show that a $6k tool nets $50k in productivity or quality or speed they have no problem selling it. Companies will take the easy-but-expensive option over a cheaper alternative. The problem is that's really hard to measure and seemingly they've put no effort into trying.
