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.
3.5 months.
Also, you'll be hard-pressed to find much upward pressure beyond free on this list: http://en.wikipedia.org/wiki/Comparison_of_feed_aggregators
"except instead of taking advantage of their monopoly". Woww way to telegraph the fact that you completely misunderstood the Internet Explorer/Netscape issue. Parallels with IE/Netscape are meaningless if the monopoly _gets thrown away_.
Sounds like the case.
On consideration, I'm a big fan of Google, Apple and Amazon. The thing that makes me (and probably others) nervous about all three is that they are too big. For instance, a monopolist strategy (Microsoft style) might appear someday.
I just don't want to see Google dominating the world. Competition is nice.
