There is currently a difference in business interest for VPNs and ISPs. ISPs sell your data, since people mostly don't have much choice here anyway. A VPN service who becomes known to share data can probably close their business soon, new ones will quickly fill the void. They have less infrastructure requirements than ISPs and a subset of users with different expectations to privacy.

So yes, I do think there is quite a difference, although you should still be critical of your VPN provider.
