Wonding about running a background program that just performs a low level of random reads and writes to the SSD, or driver-level mitigations to add random delays to disk activity, to obfuscate the contention patterns. Though I think that adding random noise to channels like this doesn't really prevent the attack, though might make it more expensive.
Tracking people individually and selling that data is so profitable that even with the hardened security the financial incentive is significant, so maybe we should also add fines and other forms of costs to the other side of the equation as well.
Most of us probably have some form of that going on already with the different apps and services we have running.
