Yea, but not really. The algorithms are available for free, but they don’t do anything useful by themselves. The RNN is built by training the neural net, which uses grading/classification of training data to increase or decrease millions of coefficients of a multi-layer filter. It’s the training data, the classification feedback and the processing power that actually creates the AI.
A few massive differences:
You opt-in to targeted tracking with Apple. It’s impossible to opt-out with Google. Apple also enforces per-app opt-in for tracking.
Apple use your data, but they don’t sell it on
Apple features protect you from 3rd party tracking at a software level (Private Relay) and hardware level (MAC randomisation)
