Is Opera VPN safe?

Opera web browser has a VPN available, but I don’t know if it’s safe to use, what do you know about it?

Opera was outed for selling user data before and offered extremely high like 130% loans to people.

I wouldn’t use any free VPN service. It’s not safe to use…

At the end of the day nothing is truly free. If they’re offering a free service it’s likely you’re paying for it with your data.
