This has two logistical consequences: 1 - it's more valuable to launch a new product that it is to successfully maintain/grow a current one. 2 - the person running these new projects tends to get promoted away, leaving it rudderless.
Google could change all this overnight by restructuring what these review boards prioritize.
This is very stale information at this point. Product launches are now pretty heavily gated, and promotion criteria are far less based on launches than on overall impact, including but not limited to improving/maintaining products.

(Also a Googler.)
So, two things:
1) Changing culture is really hard, especially at a company the size of Google, and
2) Even if they could change the culture, it's possible they simply don't care or they believe the benefits outweigh the cost.
If you don't believe it, try selecting 10 of their supposedly killed products at random. Had you honestly heard of them ever before? Do they look like something that would have had a significant user base? Hell, do they even look like they were actual products?
Always building new infrastructure, and not maintaining the existing one.
Sometimes they stumble upon something another PA needs, but often it just ends up as a patent or research paper.
Who can divert from Google's massive ad income funnel?
Apple.
Facebook.
(Also maybe several foreign governments' antitrust cases.)
An engineer on your payroll is an engineer not on the competition's payroll.
Guido van Rossum (creator of Python) is a Distinguished Engineer at Microsoft. Before that, he worked at Dropbox.
I get the quarterly check-ins from the "alumni recruiting" team, and can assume Guido does too.
"Zircon is the core platform that powers Fuchsia. Zircon is composed of a kernel (source in /zircon/kernel) as well as a small set of userspace services, drivers, and libraries (source in /zircon/system/) necessary for the system to boot, talk to hardware, load userspace processes and run them, etc. Fuchsia builds a much larger OS on top of this foundation."
