Yes, all of the VPN providers that I recommended (Mullvad, AirVPN, IVPN, AzireVPN, and OVPN) are privacy-focused and make efforts to protect their users' data.

In terms of open-source, some of these VPN providers use open-source software in their applications or have open-sourced parts of their code. For example, Mullvad and AirVPN are both open-source VPN providers, while IVPN and AzireVPN have open-sourced parts of their code.

It's worth noting that using open-source software doesn't necessarily guarantee a VPN's security or privacy, but it can be a useful factor to consider. Ultimately, it's important to do your own research and read the VPN provider's privacy policy and terms of service before choosing one.
