It saves them money in the same sense it saves every other information source money, it reduces traffic. But just like other sites can’t serve ads without traffic, Wikipedia can’t prove its worth and ask for donations without traffic. Eventually, people will start asking themselves why they need to support Wikipedia when Google’s AI tells them everything they need to know, unaware that Google’s AI can only do so because it scrapes Wikipedia without paying for it.
If I remember correctly, you don’t really need Prowlarr. It’s useful if you’re using multiple *arr services, but Prowlarr manages your indexers, the place *arr services look for content, and syncs them to your other *arr services so THEY can do the search. I don’t think Prowlarr itself ever looks for content automatically, only if you manually search through Prowlarr.
