! is a single, slender character that’s easier to gloss over than not is

[gildor]

It’s hard to follow if you have ! on start of long expression or chain of calls

So not as part of last call is more natural to read, compare
!something.isNullOrBlank()
=
not something is null or blank
and
something.isNotNullOrBlank()
=
something is not null or blank

not as postfix also work, but reads not so naturally:
something.isNullOrBlank().not()
=
something is null or blank not
