But I don't support using ad networks in the products that are not big enough to sell them themselves. Firstly, because it makes those products completely dependent on third-parties for their own existence. And secondly, because these products often become proxies for third-party user tracking.
Just let me pay for your product, if I like it enough. Otherwise, I will just rely on Blokada[1] to protect me from your unwillingness to find a sustainable business model.
