IP is often enough to correlate things. LittleSnich or whatever is no help - oftentimes data is collected by the app/site directly, and then funneled to various systems via kafka-like brokers. In this case you always have only cobbections to something like cool-application-domain.au

LittleSnitch also does filtering, so it's both parts of the solution: it allows inspection of outgoing connections, at least by domain, and filtering of those connections you don't want, allowing you to block ads and most data networks.
