> PredictWise has collected hundreds of thousands of respondents reporting party identification and models voters through survey, mobile data, and location data compiled through mobile devices
> PredictWise’s database includes verified data on 50 Million+ unregistered voters, sourced through credit files and portal registration data (e.g. Crate&Barrel), and is carefully purged of duplicates or registered voters, updating daily. PredictWise (PW) machine learning models predict the party of unregistered based on survey respondents from hundreds of thousands of Americans and can apply support scores to turnout your electorate.
> We make full use of the probability models on the file, ensuring that each individual will get a score reflecting his or her exact position. The end result is a continuous score for each cluster ranging from 0 to 100 for every American represented on the file.
So, they have a few hundred thousand survey fills/app installs. Then they combine the data against 50 million public records, and then they extrapolate it out for the entire voter population. So they may have one or two given devices in an area and then their model says what that represents across everyone.
First, people were willingly installing COVID-19 contact apps to alert them if they were in contact with a confirmed-positive case. Despite all of “us” (security-paranoid people) shouting at the top of our lungs that This Is A Bad Idea.
Second, your phone is constantly listening to a list of SSIDs and bluetooth identifiers to connect to and broadcasts a small amount of info - like your MAC address -, which can uniquely fingerprint your device. Supermarkets, for example, have used this for years to track shoppers. They can easily track your phone without GPS just by listening what it broadcasts and where from. And it is also then not a surprise when Apple decided to remove the functionality to turn off WiFi and Bluetooth from the “drawer” and instead of for it to only “disconnect from nearby networks until tomorrow.”

In most things I would agree to the adage about those who would give up their freedom for safety deserve neither freedom nor safety, but the right to not share my location data to help people be aware of a deadly pandemic and protect themselves is not something I would consider a freedom, and it was given up to protect other people's safety which is a noble cause.
If that's a step towards hell then God is not good.
But you don't get to make that decision for OTHERS. If you are worried about COVID, stay home and wrap yourself in a bubble. There's a certain amount of risk that comes with living with people.
And the rest of us don't have to inject untested, unproven chemicals into OUR bodies just so YOU can have a false sense of security and virtue signal.
Freedom all around.
