Many many Android users are terrified of apps that ask for AccountManager-related permissions, especially the Manage Accounts permission if an app wants to use Android to store their own credentials. Developers don't want to scare away people who are unsure about certain permissions.
The widely adopted solution is to explain permissions clearly (eg text in app description or link to a web page).
In this case I wasn't even talking about the Trello apps storing credentials in AccountManager - I meant it as a client of the AccountManager to let me use the existing credentials the device already knows.
"Your antivirus software may have flagged the exe in this zip as malware. Please go ahead and click continue to enjoy the great experience we have waiting for you."
Yup. I just downloaded it and signed in with my Trello account name. I was actually thinking to myself that it seemed like a really pleasant sign-in experience (they provided a nice list explaining permissions). I actually came away happy. Imagine that.
... and $900. So much for enticing developers to come. A first come, first served with a much higher price means it's more likely non-developers will come.
