It's more likely that if you are trying to claim on your insurance, they will ask you "have you driven for a ride-share service at any point since the start of your policy" and deny your claim if you have. And presumably it's fraud if you lie on the claim.
Yes, this. I was involved in an accident a few months back and adjuster for both companies asked if I ever used this car to drive for a ride sharing service. I don't recall it being limited to the duration of the policy though.
No, that's not what was meant. By "was ever used" they mean "if you, the policyholder, ever used this vehicle for ride sharing while insured by the company"
If you buy a vehicle used for Uber/Lyft but you don't drive for Uber/Lyft then there won't be a problem.
