Google Maps is one of the sites I still whitelist, but I often reconsider this decision, and I'm ready to find a replacement.
Today's Google Maps is a shadow of its original self, which did have a no-JS version, by the way. It has gradually gotten simultaneously heavier, less convenient, more annoying, and less useful, and I've just about had it.
Just off the top of my head, it no longer displays zip codes, takes a long time to load, has missing street names on the map, often promotes features I do not want while taking away features I do want, and is covered so thick with paid-promotion items that I can barely find somewhere to click that isn't an ad.
