Vpn suspicion,questions,and opinion

gistfile1.txt

When i was browsing on the internet to find a free vpn (Yes i'm poor) I saw this thread that talked about
Not to download vpn so i read it just matter of a fact i have some questions
First:If vpn's are loggers then what can protect us on the internet.
Second:How can we acess websites like go90 or other websites 
So these are the 2 questions now my opinion of vpns
Now lets start with the free ones
Its very hard to find a real free vpn that allows you to acess anything without mb running out
And thats annoying.Like this is what made me hate on vpn
They beg you so hard to buy there product.
Also not just that they also have no unlimited acess instead you have to keep on paying like bills
Vpns are great and annoying at the same time
Now the suspicion the main topic
I think in my opinion vpn has nothing wrong just when i read this thread
I uninstalled my vpn 
But i feel like vpns are trust worthy in my opinion
But thanks to the guy who alerted me about the vpns aka joepie91 credits to him
Also here is the thread that he made

Anyways i'm now aware about the vpn thing
Tell me are vpns safe or not?
