Of course. Storage space is cheaper on 7200rpm drives, and has, historically, for years. SSD is rapidly dropping in price, but it's not on the same level, yet. Western Digital Gold 4TB is $150 USD. Crucial MX500 4TB SSD is $200.

EDIT: SSD is also not available for large drives, 8-20TB.

The way that Christian and other developers were treated by reddit, their administrative team, and their CEO, is just abhorrent. There's no justification to explain their behavior. It's just so cold. To attack someone from a position of power for simply defending themselves, after attacking them for a mutually beneficial compromise, is just morally bankrupt behavior.

I don't blame him (and others) for just wanting to stop the relationship with reddit. Even if they backpedaled, there would be no trust left.
