I wonder if the author writes this content for free or if they expect to be paid. Given Ghacks' privacy policy where 12+ categories of personal data tracking are in use, including precise geolocation, I suspect they do expect compensation for their work, and that it is funded through targeted advertising that requires surveillance tech and data gathering.
If the choice is between publishers setting prices for their products or readers being forced to unwillingly participate in the advertising surveillance industry, I'll take the walls.
But there probably is no such choice. The money Ghacks makes collecting and selling sensitive personal data is probably so sweet it couldn't be replaced by subscriptions.
Just saying, the author should probably think a little deeper about their "free for everyone without restriction" idealogy.
