I’m using it too for now, but considering stopping. afaik the tool is not open source (even if it is, still happy to pay for the app), and to me feels a bit too magical and makes me uneasy. I have no idea what it’s downloading, what lists it’s fetching, what kind of content it’s blocking, what it’s blocking on a specific site, whether some site is broken because of it, or even if it’s working at all. I do like how in ublock (or brave), it shows some info like number of things blocked on current site. And then in ublock you can go arbitrarily deep into logs / custom blocking etc.
For Wipr 2, on macOS you can see the rules here: `~/Library/Group Containers/group.wipr2.rules/Rules/` in the JSON files. Kaylee (Wipr dev) sources the blocker list data from these [0] sources.
