Even if you assume that VPN provider is listening and analyzing all your traffic, it's still preferential to your internet service provider doing the same thing. Fost starters, the internet provider just knows more about you. You probably have a contract with them, they know your exact physical location and they have your SSN. A malicious actor from within internet provider having access to all this information could potentially blackmail you by revealing your porn logs to your spouse, or your unsavory private reddit history to your employer etc.
Second, your VPN provider could be in a different country, and that would make data mining your traffic slightly less interesting to them. It'd also make data acquisition via subpoena of some sort from your country slightly more bureaucratic.
Third, if you have reservations about your VPN provider, you can just cancel your account and go to a different one. Changing VPN providers takes 5 minutes, while changing internet service provider can take months, or in some cases might not even be possible.
