Sorry... if you are making money from your site (even with ads), you ultimately are not providing it free. If you want to see an example of true "providing it free" you can visit any site that does not force ads on you or subscriptions to access certain content (mine for an example). I do realize that if my site grows exponentially that attitude will have to change after it exceeds $200 a month to support (the amount which was set by me as excessive monthly expenditure for a hobby). But that's a long way away for me currently, and generally if your site is costing (self hosted) more than $200 a month you have entered the level of a business. Your statement does prove my point. At one time folks were not so concerned with making enough to "pay for the site". It was more about sharing the information for free (real free, where you were not subject to ads or any of the other money making silliness).
That was my point... yes, it does cost money... I pay it every month and in yearly renewals. But I choose to not run ads nor gateway content.
