The argument seems to be "since VPN does not provide perfect security and privacy, you should not use it". This is obviously a fallacious argument - you need to evaluate "using VPN" vs. "not using VPN", not "using VPN" vs. "using some perfect theoretic unicorn privacy system that nobody has". Yes, VPN providers can track - but they make it harder to track you to third parties, unless they are in collusion with those parties, but for average user the chance this is happening - unless they are on the FBI/NSA radar already - is pretty low. Yes, third parties can fingerprint and use other techniques to track people. That's not the reason to offer them the most easy and readily available means of tracking on a silver plate.
