For all these reasons, we call on HP to take the following five steps, immediately:
1)Apologize to your customers, and restore the original functionality of their printers with a firmware update that rolls back the self-destruct sequence;

2)Publicly commit that you will never again use your software update process to distribute anti-features that work against your customers' interests;

3)Publicly commit that the effects of any software updates will be fully disclosed;

4)Prominently disclose any capability or plan to remove features from devices in your sales literature, so customers know what they're getting before they buy;

5)Promise to never invoke Section 1201 of the DMCA against security researchers or competitors who make legitimate aftermarket products.
