Well... One of the best selling paid versions, Crystal, is going to allow companies to pay for &quot;acceptable ads.&quot;<p>Personally, I think the people who paid for blockers were ripped off, there&#x27;s nothing special or difficult in building a content blocker:<p>1. The majority of the value, the blocking list, it readily available and actively maintained.<p>2. Performance and integration into iOS is provided by Apple, you simply produce a format that Apple approves.<p>So what are you paying for? Marketing, packaging, and giving a 3rd party control?
