argante It's no a secret that the data centers where VPN servers are hosted can collect data, and they need to monitor the network.
Data Packet and M247, to which you often refer, are useful if you're resident in the USA or Canada, because Mullvad has a lot of servers in its geographical areas that use this hosting providers, that said, if you're an EU resident like me, just opt for hosting providers like Blix or 31173 Services AB which host some of Mullvad's proprietary VPN servers, so it depends on the use case, I don't use Data Packet and M247 with Mullvad personnaly, anyway, hostings providers don't have access to Mullvad's servers, even for the servers Mullvad rents.
