Sounds to me like another nail in the coffin for Arduino as a useful tool for hobbyists. That said I stopped buying Arduinos years ago and started buying super low cost ESPs from China and I think most other people did too so I guess it's not going to be a huge blow
> super low cost ESPs from China Just checked aliexpress.com. You were not kidding - $1-2 per item!
At this point Arduino is just extremely overpriced and probably only still relevant because it's a household name and people want pin compatibility with the Uno and V5 tolerance for reasons.
