GPU mining has been mentioned several times already. It was not a secret. I guess no everyone reads everything.
Sorry to miners who don't like the launch so far. Sia is no bitcoin. They could wait another 2 months to make better smoother launch. They can also wait 4 years to make even better launch.
This is new raw disruptive currency that needs to be out in wild right now and get it stable fast possible. To make it the worldwide storage it wants to be. Nobody care to make you happy miner.
Sia try to be working storage business. We need help community in beginning. We all needed to get this going.
