Earlier quoted context omitted.
While I agree with the statement, lately Google's action has been concerning (with things like Reader, Google+ push, and what not). I just don't want to see Google dominating the world. Competition is nice.
Are you implying that google did a disservice to the competition by creating a desire for a product and then retiring it with months of warning for competitors to develop their product and attract google's large user base while allowing users to easily migrate their information to those services?
There are parallels to the Internet Explorer/Netscape issue. Google provided a free service to everyone, killing any good paid services/products (which didn't integrate with Google Reader), except instead of taking advantage of their monopoly they just threw it away.
Now you have companies like Reeder, with a sufficiently large user base, who have to not only scramble to provide their own backend (or integrate with someone else's), but also scale it to the appropriate number of users literally overnight, which is not necessarily an easy task for a company which has, so far, only needed to have client-side developers (which is why most client apps, like Reeder, moved to using some other company for their backend instead of writing their own).
There was certainly no malicious intent, but they basically crushed an entire market and then abandoned it.
