Great points. Also, to me that 'bit' is a fraction of 'bitcoin' is a strike against using 'bit'... I'm pretty sure that borrowing 'bit' from the fact that other currencies have historically used it isn't necessarily a good thing, either.
I'm not opposed to coming with another term for 'sat', but this push to force a change is stupid. Just start using another term if you want. If it organically catches on, great! That's how language actually works... not by fiat.
