If you don't understand the consequences of your argument, people will regularly complain that your argument makes no sense.
They spent large amounts of money preparing and operating Google Reader. There is no other way they could possibly prove to you that they took it more seriously, short of throwing MORE good money after bad.
They watched the growth curves, they added features (reader.google.com/play for one), they integrated with other products (Buzz), they waited for new products to be released and integrated with them as well (Google+).
At some point, they decided to leave the market.
Or they should have shut it down sooner? Before they added those features, before they integrated with other products, before the other products were released and before they integrated with them?
Taking it seriously = more time, more money.
Shutting down sooner = less time, less money.
It's apparently OBVIOUS to you exactly how much money they should have spent on it, how they should have prioritized their new features and integrations, and the precise date at which they should have shut down.
And it's so obvious to other people, that they get ultra pissed about it, and abandon all other Google products out of spite.
I wish I had your crystal ball.
