Standards support is a big one.

Early Google took pride in following other people's standards and avoiding walled gardens: XMPP, RSS, semantic web/micro-formats.

Today's Google avoids traditional standards and many standards that don't originate from Google, doesn't mind walled gardens in their favor, or "standards" that they (almost) solely control (AMP as an obvious one, HTML nearly with the Chromium monopoly), and doesn't even use standards in many areas where early Google thought it important (communications apps that might use something like XMPP or Matrix to federate, for instance).
