This is just a play to nudge apple to reduce prices by trying a new anchor
Not really, this is just them copying Apple and Google. This fee reduction only applies to developers making less than $1 million per year in revenue, which IIRC is the same thing the others are doing. (although to be fair, there probably aren't a ton of devs making more than $1m per year on their store lol)
I think this is most likely a ploy to stave off regulation. In other words, they're doing the exact same thing Apple/Google are doing for the exact same reasons.
Why would you assume that? I don't know if there are or not.
If you have, oh, 5 or 10 developers working for a company, it better have $1 million/year in revenue to pay them all.
I don't know how many entities selling apps in an app store have more than 5 developers, or otherwise how many have more than $1 million in revenue.
BB10 launched with Android compatibility, IIRC. I know that the first phone they released with it (BB Z10) had it.
