This. Everybody knew that those blades were hugely overpriced and there was no return in buying them.

Let's be clear. They just sold some dozens of them. Mostly to newcomers. If they were priced reasonably, you would have seen single persons buying hundreds of them and building big set ups based on those units. That didn't happen, because the blades never made any sense from a business point of view except for ASIC miner and their shareholders. Those units were just a very unprofitable toy for the customer.
