Google log the MAC addresses and IP of the whole network if you ever use google support phone in that network. For example, the YouTube suggestion for the whole network is the same even after you change the network public IP by using VPN or some sort of thing.
imo still better than any other providers. the only thing bugging me is they should accept payment in xmr(which is untraceable). there is an alternative (ivpn.net) which is a little more expensive and accept in xmr but i've never tested out.
