Just to pick one of these: google Flights sucks. It had a better competitor - Hipmunk - which went under because Google ate their lunch by integrating flights search into the main search product. Don't know how many of these Google products have similar stories, but it's probably a non zero numbers.
What we're getting, in many of these cases, is an inferior product that drove out better competitors through Google search integration.
I remember Hipmunk, it was horrible! Google flights is by far the best flight search platform, competition aren't even close. 10x faster search of flights and the calendar view for prices is incredible!
I consider Google Maps to be the best application ever created. Products like Google Mail, Calendar, Search, Chrome, Android are absolutely best in class. To call them inferior is laughable.
