Via media intervention? Eh. That concerns me and makes me worry that 99% of the time this happens it silently goes away from a customer who is not able to get media attention.

IMO this should be a flag for regulators to start taking a look, too, to understand how systemic this is.

Out of all things such as app store monopoly abuses and taxes, right to repair abuses in both devices and cars, search/ads monopoly power abuses, consumer protection is already reasonably and well regulated and not the first thing that needs additional regulation.

There's already decent regulation, yes. It may be time for the regulators to actually look at Amazon using those extant regulations, if they are declining returns in clear-cut cases like this.
