Consumers actually want to use services offered by companies, and willingly accept what you consider drawbacks. We want accurate traffic data in maps, and crowd-sourced key finders, and all the other conveniences afforded by unspoofable location data, and we give up a little bit of control in exchange for that.
Companies don't compensate us with money for crowdsourced data; they compensate us by offering services they couldn't offer otherwise.
The ‘us vs them’ mindset comes from ‘then’ determining what is acceptable for ‘us’ to do purely because it’s good for ‘them’.
If I want to set my location to somewhere I am not, and the only reason I can’t is corporate interests, then a battleground has been drawn up by those interests, not me.
Companies in general don't want reliable data for the fun of it; they want it in order to provide services that users want.
Since I paid for my phone, I really don't see why it's incumbent on me to help the latter case out. A delivery company is free to supply a managed device or fit a device to their trucks. A crowdsourcing company should in any case already be assuming all client data is suspect and ensuring it's properly correlated with other sources of information.
There's no fraud here. The worst case outcome in your list is perhaps a delivery agent just having their phone say they've done a particular route when they just sat in the movie theatre or whatever, but the fact that none of their packages got delivered is enough to out them even if the shipping company is trying to get location data for free from a device the shipping company doesn't even own.
If I hire a bike I'm nowhere near I still pay for it. Denial of service attacks in which the perpetrator is fully responsible for the cost of resources consumed just aren't a thing that happens.
The only group involved in these scenarios that's taking adverse action against another party for their own gain is the entitled companies demanding users' phones be locked down so they can continue to get material gain from them without compensation. The net benefit here is that these companies' profits should definitely be taking a back seat to users' rights.
