Big Brother air monitoring.

Yes. Of course. Just avoid any cloud-based device if you can. Their whole underlying business model is to make money off your data, one way or another. On top of that, leaks do happen. Quite frequently.

It's become harder and harder to find such devices that are not cloud-based, though. Air monitoring, even just thermometers. But that's when being an EE helps. If you can't find anything that's only local, you can make your own. Something I do recommend.

predatory industry wants subs  :-\

I feel violated by all the stuff that wants my smart phone and internet to basically do nothing useful

anyone else been alot less interested in gadgets now that its "hi, we can sell you this malfunctioning plastic shit that will break in 6 months so we can train our AI. this time it has a slim RECTANGLE shape!!" ?

Even after he was tested and cleared by the FBI; and after they were able to prove that the original testing company had an error rate of nearly 40%.

   Mandatory testing or any testing without your prior knowledge and consent isn't as simple as most people think and may have serious implications FAR beyond what you ever imagined.

I'd say this highlights a glaring issue with the system in your country, not just how testing is conducted. That kind of crap just wouldn't fly here. Same with testing drivers of motor vehicles for either alcohol or drugs (which I've done many times, the testing, not drugs). The burden of proof is high... very high, and even then the courts let them off half the time.

I'm not suggesting that all testing is 100% infallible, things oral fluid tests (for example) are used as an indicator only. The process here looks something like this:
1. Person is tested with a handheld device to indicate the possible presence of a substance.
2. If positive, the person undergoes a second test using much more sophisticated equipment to confirm presence and concentration of substance.
3(a). If positive again, legal process is commenced. The original testing fluid is sent for lab analysis for confirmation.
3(b). If negative, the first test is deemed invalid and no further action is taken at this time. Testing fluid is sent away for lab analysis.
4. The test subject has the legal right to have a doctor take blood, for the purpose of further, independent testing.

No one, and I mean no one should lose their job or driving privilages based on an initial indication.

My response:  "No.  No sir it is not 'just' that, not even close."  From a single sensor of this calibre in the house I can tell a whole LOT more than my air quality.

At some point it becomes unsettling, yes. 

Honourable companies are not obligated to stay that way, either.

I wonder if there are any studies around deliberate data tracers.

The way you would give someone a radioactive tracer to drink so you can then watch it propagate through their body.  Just for data.

What I would be looking for is a way to visualise how far, how fast and how diversely the data "radiates" ... or does it (more likely) arc and randomly traverse long links rather than spread evenly...   does it "grow" outward like fungus?

The marker can be something clever and mathematical that will survive attempted redaction etc.

The hardest part is getting the "scan" data of where your data has got to. 

Ironically, the best reliable source for that data is Tor and the black market.  This would (maybe) make the study taboo?
