Fyi, while Nordic products are usually excellent, they did not design the wifi ics. They bought a company and slapped their name on the chips. I haven't used them yet, but from what I've heard they don't live up to Nordic's standard.
Edit: also afaik they don't have a mcu+wifi in one yet.
Because the prices are not competitive enough for hobbyists. How can you expect people to adopt and develop on top of your chips if they can't afford it?
