Your threat model for ubiquitous cheap sensing tech is nation states? I'm not overly worried about being spied on by nation states. In general, my feeling is that if a nation-state decides I'm important enough to deploy hardware against, I have no real defense.
Now, big tech companies putting it everywhere, and either convincing the stores I shop at or my neighbors to pay for the hardware and slurping up the data - that is a real danger case. And those companies build off academic research like this. Even trillion-dollar companies don't do as much of this research inhouse as they do by sponsoring grants like this.
