The text is written in such a way to make you think that indeed Apple themselves do the same tracking which they blocked for others. The opposite is true. Apple don't track users outside of their services. Apple tracking inside their apps has always been opt-in. Meta, Google, Amazon are still free to track users inside their ecosystem, but outside tracking has become opt-in.
