Google maps is
* Much, much slower than it used to be. My machine in 2012 was able to drag the map around and everything would load just fine.
* Harder to read/understand, especially street names. A lot of the time I have to zoom in 100% and scroll up and down a street to see what the name of the street I'm looking at is.
* Much worse at text parsing e.g. I can no longer loosely type something like "10th and grove to Jim's Hardware" and get directions. In fact most of the time I can't even type in a major intersection and get what I'm looking for.
* Obnoxiously spammy: they push new "features" on me all the time that I don't want to use (including a recent popup mid-directions when I turned on location tracking because I was lost on a busy, complicated highway intersection. It felt pretty dangerous, getting confused by a popup in the map like that mid-intersection), and the phone version asks me to turn on location tracking EVERY SINGLE TIME I OPEN THE APP.
* Addresses seem to be getting replaced by some weird google maps-designed address format in Colombia (maybe other countries?) that are useless to humans
* While every good review site seems to fail for whatever reason (tough to monetize, and fighting spam/fraud is also hard?), Maps seems to have become the de facto review site in many places. But the UX is so godawful I can't even wrap my head around it. For example, search for a restaurant, and you get one (ONE) possible filter in browsers: star rating. There's also a "more filters" button which brings you to a separate view where star rating is the only available filter. On the phone app, sometimes I can select "open now," and a few other things about 20% of the time I use the app, and it's not clear why those options are gone the rest of the time...
I think it's a real shame, because I remember in, e.g. 2012 I thought Google Maps was an incredible revelation. It was so much better than MapQuest, it was free, fast, and just worked. If only they had open-sourced the old version before the refactor...

Anyway, I hope someone writes a nice open-source view layer that sits on top of OpenStreetMaps someday. Like a wikipedia for maps
