Depending upon what you are trying to do (anonymity or privacy), the answers can be different. I am trying to maintain privacy so I have my own VPN server in the cloud, on amazon, digital ocean, etc, where I control the server. Of course, my VPN server ip address is associated with my account so it is not completely anonymous, but at least until it exits the VPN service is it private. The question to what is the cloud provider doing? They are certainly doing monitoring, but are they tracking? Given that their business model is to provide cloud services and not necessarily selling data of the businesses that use their service, the risk of data theft appears lower to me.
