A lot of these are pretty silly. 100% of Songza features were rolled into Google Music. Listing every phone they no longer market doesn’t make a lot of sense either. You might as well list Maps for Series 60 phones if you wanted to get down to that level.
(googler on maps here)
the maps backend team makes an explicit effort to keep old things going, I wouldn't be surprised if old gmaps on some really ancient phones still worked.
Last I checked the pre-2012 Apple Maps (the one that used google tiles, iOS5 and below) still works.
Having all the Android devices they no longer sell is also pretty silly. I doubt anyone wants to buy a Nexus One today. Also Nexus Q never made it past user testing (they never sold them, they were a free gift for IO, it was a horrible Chromecast/Nexus player precursor)
Well, it was sold, and then unsold. They took money for preorders, and then changed their minds and gave everyone who preordered their money back along with a free Nexus Q.
Creator here. And I agree. Listing every phone is silly. A lot of these were added during Hacktoberfest. Going to go through and prune/combine/edit this weekend sometime.
