My guess is that AMD need the market share. If you have a superior product, then it makes business sense to flood the market at a cheaper RRP. To gain that market share. As people tempted, will need to get an AM4 or AM5 board.
you can have a superior product all you want. if someone has a similar strong product at £500 you dont sell a better product at £200. anyone who believes that is in cuckoo land. thats why all cpus gpus are priced accordingly.
