This is stupid. The entire point of the electoral college is to ensure small states have a say and the country isn’t ruled by the majority mob. Small states would have to be pretty ignorant to make themselves irrelevant like that.

We see that that backfired. :)
The states that would arguably be stupid to go for this are actually the purple ones rather than the large or small ones, because they are the ones that are currently the focus of presidential campaigning but they would no longer be if there was a mechanism for making the EC reflect popular vote. That's perhaps why Colorado may remove itself (see https://fivethirtyeight.com/features/the-movement-to-skip-th...)
Without the electoral college, "states" collectively don't get any say at all. Only citizens of those states.
