The app might be GPL, but it’s a paid app. I see no reason to submit a PR to do the work for the developer. I am also a customer of his, so I don’t think it’s unreasonable that I had hoped he would make his app fit for purpose. If I raise a PR to help his LLC sell apps, I have no control over whether he will actually accept changes or submit changes to the App Store, either. I don’t intend to give my time away like a charity to an LLC.

I wrote my own app to determine whether Safari had implemented enough of the properties of the declarativeNetRequest API to allow for redirects. It turns out that it does, and in this way, it avoids reaching destination servers and avoids cookies they may set or analytics they run, and counts towards MAU. It also works with DNS blocks to target sites.

If I release it on the App Store, it will be free.

In any case, I said nothing bad about the developer except that they are aware of the new API but have not shared plans or shown motivation to adopt it. That’s not a negative comment and does not detract from the possibility of significant life events etc. It’s simply an observation.

It seems like you’re crafting a straw man out of a few words I shared about a privacy app.
