Neither side especially comes off well in all of this. 9to5mac misspelled his name? I don't see how that's especially funny (and it is childish), but Arment needs to lighten up about that. I also don't see how even the accusations regarding the servers the FBI seized hold water, but there is a polite way to deal with it (read: not blocking a site and making it look like anyone but you is at fault).
Ultimately, I'll still use Instapaper as long as Arment keeps making a quality app and keeps his personal choices out of what I see in the app.
