You don't control any VPN services hosted on someone else's (e.g. a cloud provider's) infrastructure
We must have very different definitions of "control".
They have full access and can technically do anything.
You could say the same for anyone with physical access to a machine. But the people who have to worry about that likely aren't reading this.
And they see your incoming and outgoing connections.
So does any bandwidth provider you pay money to.
This is stupid, and doesn't give you any privacy benefit.
Highly debatable and subjective IMO
There are good and trustworthy VPN providers
Depends on your definition of trustworthy... some say it's impossible to trust any company.
