it is probable that you don't get the deepest pockets by wasting money. anyone that pays so much for memory means they expect to get even bigger value from that.
This is a misunderstanding of bubble markets to an extreme degree.
In a bubble market where B has massive amounts of capital allocated to it in a way that will likely collapse in the future than it's very likely they will never recuperate the 2M they put in the RAM. Instead buyer A that would get at least 1M of usefulness if not more, gets far less, crippling their business. Then when B collapses a ton of RAM is dumped on the market for far less than 1M cratering the RAM providers business for years.
No? It goes to the buyer with the deepest pockets.
