Then when audit team is gone, they enable user logging. I think thats a possibility in every provider. IMO based on the transparency they handle police requests to get access emails, I will keep using protonvpn.
Source? They've always been logless. I think you have this completely backwards considering Proton maliciously logged and handed out customer IPs to police [0]. [0]: https://techcrunch.com/2021/09/06/protonmail-logged-ip-addre...
Note also, that the case pertains to Proton Mail, and not Proton VPN. Proton Mail is considered to be a communication service, and in most countries (including Switzerland), communication services are regulated to some extent. The treatment of VPNs is different. There are no Swiss laws compelling us to log IP addresses, personal identifiers, traffic or browsing history, as proven in a 2019 legal case (we were not able to provide the requested information because we don't keep any: https://protonvpn.com/blog/transparency-report/).
