What I have seen is upstream ISPs and international carriers charging fees
when the sub ISPs request receiving the global routing table. There have
also been numerous occasions where such fees are charged given reasons like
"we also have to contact our upstreams to allow your prefixes".

Others also simply dont have well designed core networks to tunnel huge
global BGP table to their clients. Anyways these days many ISPs have
routing gears which could handle enough traffic than where fast FIB becomes
a problem as you pointed out. I do agree with you tough that having routing
gears with distributed FIBs implemented on ASICs (which are expensive to
own) for speed might be a better reason to charge the clients - BUT in many
cases as you stated it is not warranted.
