True companies do not pay per packet but they do pay for the bandwidth. The more users that use more bandwidth consistently means the ISP needs to invest more money on throughput/links. If you have 100 users and they use 1 mbps on average you can get away with a 100mpbs link. If you have 5 users using 50mpbs on average now you need a gig link. So technically it’s not free but yeah bandwidth caps suck big time. My suggestion would be to pick a place to live near a city with a municipal broadband option.
