Specifically, all the issues being discussed are actually just features of Google (and the rest of FAANG really) being a mature company in a mature industry.
Google cannot (it seems) launch and maintain new services. Why? Because it already has a single, ultra successful, profitable service: advertising (primarily via search, gmail, youtube etc). When you have no existing business (say you are a start up) you have an urgent need to get one. But when you have a multi billion dollar core business asset (search), you have no urgency to create another. Instead you "urgently" need to not break your existing asset.
This is the same reason GE and AT&T etc did NOT beat Google to the online space.
This is the natural result of success.
This is the healthy, efficient, economically correct position for a company like google to be in.
People have a weird expectation that Google (etc) will be a start up forever. Or an incubator for start ups. Only thats basically functionally impossible.
So the problem here is people's expectations not being realistic and refusal to accept the reality that google (with 175000 employees) is no longer a plucky 10 person startup...
