Yet, with busy.org, I can log in with my posting key. Why do we have to use owner or master keys for DMania?

I have noticed this on a number of other projects claiming that SteemConnect only allows for owner or master key logins. Therefore, something doesn't add up.

Some of these projects are very interesting, but I will not use any of these services that require login with owner or master keys. It is insecure.

Remember, that is the whole point of blockchain and crypto space, to be trustless. We should not have to trust your service that it is not storing or using our owner or master keys.

So if Busy.org can do it with the posting key, why can't DMania?
