Ctrl-c does the same and it is easier to press.

it's not 100% equivalent, for example C-v (select visual block), I, ..., C-c will cancel the block prepend action, whereas esc or C-[ will execute it.

Took me a while to realise that when messing around with visual/block.

I still mostly use C-c from muscle memory though, but do occasionally swear at it.

I see this caveat all the time, why don't people just rebind C-c to Esc and be done with it
