Sony situation is unique and, in my opinion, is not what it seems at first. So yes its true that PS5 got a massive boost from the sale, but as some have already mentioned, it seems really odd that they would be so effective where Microsoft wasn't. But keep in mind the greatest weakness of the Xbox is that something like 65-70% of their sales come from the US. That is a HUGE handicap and would come back to bite them if something were to 'happen' that increased the cost of shipping to the US.
Sony is the opposite, their sales are usually inverted in total meaning that Sony only sales about 30% of PS5 made to the US.
So in reality its wasn't that Sony ate the costs, it just that Sony was able to spread out the cost to the entire world and that is why non-US countries got a small price hike as well. And it allowed them to do a massive holiday sale for everyone.
