Speaking for myself, yes, I do consider it surveillance even if Apple (or anyone else) does "on-device" analysis. The main issue is whether they give me a choice in the matter, and control over the data collected and how it is processed. Once the data is collected, BigTech can change their privacy policy or Terms of Services to access this data any time. (And that is exactly what they have been doing). Moreover, they still need to collect some data to ensure the "on device" analysis is working as intended. (That's where the clause "we may also collect data to improve our services" comes into picture).
