If my VPN provider trades user data, the service will quickly deteriorate and it won't be a VPN provider for long. But even if that is the case it wouldn't be my primary concern.

I don't even live in a country were I have to fear much at all from malicious authorities, but they wouldn't even blink before trading privacy for perceived security.

I might change my opinion if there were actual consequences for sharing user data. I believe it when I see it.

Otherwise I just like privacy, information is power and I don't like to share with the state.
