I do this with an old phone on wifi. I don’t think it’s a huge deal. I use fetch and haven’t seen any ads or credit card offers etc. you just exchange points for gift cards. I know it’s probably harvesting some data from me, but I don’t really use that phone for much else, and I use a VPN/not my real email.



not aware of youtube sponsorships or why that would matter. I’ve used it for like 4 years now and have had no problems.
