Do you have any evidence that free services such as Windscribe or any pro services in the VPN sector actually conduct this as you state?
No, but I am not complaining that they are doing anything wrong, so I am sorry if it seemed like that. I used the word "probably" for that reason.
If you really believe that handing over all your traffic to a VPN provider is going to keep you safe from the government then you're terribly wrong (general comment, not aimed at you). Hundreds, thousands even, of criminals are caught on a yearly basis. Guess what they all have in common? They thought a VPN would hide their criminal activities.
In fact, many from the dark web using the Tor network on a Tails machine are regularly caught as well. Resources are usually spent on getting the vendors and not the buyers unless you're buying illegal chemicals that can be used to make bombs or setup a methamphetamine lab or guns. Why? Because governments silently subvert the market places and use other methods to track, including exploiting vulnerabilities.
If a government really wanted to, they will illegally hack your VPN provider and steal intelligence. Your VPN provider will probably not know about it until years after it has happened, and likely won't have sufficient evidence to prove it was government-related nor pin-point it to a specific government, as long as it is the UK, U.S, France, Germany, or another smart country with talented hackers.
If a government agency comes raining down on a VPN provider and is throwing so much paperwork at them and every law they can to get what they want, chances are the VPN provider is going to give you up. They can drop a few pounds a year and save their business or end up being destroyed to the ground. Government agencies can also make deals to keep data exchanges silent and prevent the provider from being exposed publicly from handing over the information - they will have the authority to make such deals. If the VPN provider went to court and then got overruled for handing over the information, then they'd be baited publicly, so it'd be in their best interest to just provide the data over one or a few customers and keep their business customers believing they don't keep logs nor pass data.
Businesses will always put themselves first 9 times out of 10 no matter if they say otherwise. If you have a 10 year old business, would you give up data about an alleged criminal and have it kept quiet, or take it to court and potentially get completely wrecked? I think most would choose the former, even if they claim no logs and no data sharing to all their customers at the same time.
Sometimes the marketing might say no logs and no data sharing, then you check the privacy policy/ToS you are about to sign on purchase/installation and it might say otherwise as well. Such is also things that happen from time to time.
