the day they start putting this on api implementations is the day they lose many, many sites using the api.

i suspect they get more value from the information they collect from these sites (almost all reputable travel sites that i know, both local and international) use gmaps, than the revenue they'd generate by putting their own ads on them (and risking losing these sites).

there are already excellent and very accurate free street maps available.
