Even Search has become markedly less useful, a common story around here, to the point where even nonbubbled proxied Startpage.com searches are disappointing.
Maps becomes less reliable all the time from a user perspective (in my immediate region, to cover my ass I guess).
Chromecast and YouTube, in general and in conjunction, have become...bloated, buggy, user-tracking-first embarrassments of their original versions...don't get me started on Gmail.... if you're gonna take all my info, at least be good at your services. Especially the ones I pay for.
Even having 1-5% of the search market is a pretty great business. Not everyone needs to be Google-scale to be a success.
However, it is nowhere as effective as commercial services. So much that the most effective way of finding pirate stuff is often to Google them despite all the copyright takedowns.
but they haven't built a better mousetrap, and they're up against the greatest mousetrap ever known to mankind
