Ad hominem does not change the fact that ProtonVPN admits to monitoring their users: "we check the network traffic on the server in question in realtime to verify the abuse report. If we see a VPN connection engaged in abusive behavior when we check, we find the userid associated with that connection and terminate the account." [1]
