They did that because the 2015 WC had shown that 400+ was no longer an outlandish one-off but rather 300-400 was the norm, and high 300s could be achieved with regularity. It wasn't just McCullum playing that way, Aus and SA had also put on some huge scores in that tournament.Why do you say this, btw? I would've said that ODI cricket went full nonsense by way of the England side of 2015-2019, who were themselves modelled on the NZ side of 2015 (so basically.....BazBall). That England side really ramped up the emphasis on white ball specialists absolutely slogging it on flat decks with very little "good old-fashioned cricket" to be seen. The 2015 Australia WC side I just recall as being a typically good Australia team.
EDIT: In fact you could make an argument that this series represented a real turning point in hindsight; it's pretty funny to see the headline article in that link being "yes this was a massive runfest but nothing to see here, the bat and ball balance hasn't changed, ODI cricket will be fine"
