You are still missing the point:

 

"It has to be understood that somebody has to pay the bill.  As mentioned the costs for running PZ as it is around the 30.000$ mark (without any salary) - I cannot and will not pay this out of my pockets."

 

15.000 people willing to pay 20 Euro for one year is not a realistic option?

Yes, that is not a realistic option. And 15.000 x 20 = 300.000 

 

How it is now, PZ gets exposure by being free. People can direct others in search of lens reviews to PZ in for instance photography forums. I do that on a regular basis (often to show what a joke DXO lens "test" results are).

Suppose you actually have 1500 people who would have payed 20 euros in one year. None of those can then point others to PZ results. Not all those 1500 people will pay the 20 euros the year after, even less the year after. Things will die off quickly.

 

That certain ad sellers, and certain websites using ads, ruin the user web-experience and that that drives people towards ad-blockers, I understand. That is a problem for PZ, which does NOT use intrusive ads, and has no blame therefore. 

In my opinion, all that PZ can do is make itself more visible. A .com domain may help, striving for a higher google ranking may help. You can't make the ad block programs go away, so you have to increase the amount of visitors to equal the revenue loss out.
