For those wondering why b1 isn't building this, we have to step back and look at all the pieces.
Block.one wouldn't just have to build the portal, they would have to build everything necessary for securing user's keys as well, or endorse Scatter which isn't something they can do.
By allowing the community to build this we have every tool at our advantage whether it's from block.one or elsewhere.
