Why bother spoofing when you can simply turn location permission off ?

Spoofing adds noise to the data, making it worth less.

If enough people do it in a way that cannot be easily detected, the market for this sort of data will shrink quickly.

I don't see how spoofing is better than blocking. If enough people block it, the market will shrink even faster. It's also much easier for people to block than "spoof". Spoofing seems practically pointless and academic compared to blocking.
