* It's by Mozilla, and it's more likely (probability wise) to be maintained and kept up-to-date than those that happen to be a single person's hobby project.
* I believe that big players in the web like Mozilla and EFF (eff.org) really fight for us, the common people. :) The more these things become popular, especially from bigger names, the better the chances of the whole ad-tracker-privacy ecosystem to improve for our good.
Mozilla is starting to develop a bad track record on this recently.
and in the process of fairness, any other blocker doing anything better that you plan to add to yours?
FWIW, I was never into paying for an ad-blocker on iOS since that comes with its pitfalls. I have tried a couple of other free ones, and I did like Adblock Fast [1], the one I was using until Focus by Firefox and the one I still have. It's open source and is available for Chrome (not iOS), Opera (not iOS) and Safari (iOS 9). I'd suggest reading through the GitHub page to see some stats as well as the philosophy (of not making money or compromising it with acceptable ads). [2]

the list that site provides blocks practically every single ad, malware, etc. But it is not very practical to keep up to date.
I long thought that this should be driven by a foundation , rather than a private enterprise, but I wanted the additional benefit of delegating the profits to a particular donation.
The hooks are implemented by Apple and the data is crowd sourced. I don't see any reason why anyone should profit in this space.
Because there's still work in putting it together and maintaining it? And because profiting from doing this means they're less likely to take money from an ad company?
Personally, I think the people who paid for blockers were ripped off, there's nothing special or difficult in building a content blocker:
1. The majority of the value, the blocking list, it readily available and actively maintained.
2. Performance and integration into iOS is provided by Apple, you simply produce a format that Apple approves.
So what are you paying for? Marketing, packaging, and giving a 3rd party control?
I can think of a few reasons to make a content blocker:
1. Improve privacy for users on the Internet.
2. Decrease cost and speed for people who pay for data, or have bad connections.
3. Challenge revenue streams of large corporations.
4. Fame.
5. Improve strangers lives.
