Telemetry was added to create an aggregate count of searches by category to broadly inform search feature development. These categories are based on 20 high-level content types, such as "sports,” “business,” and “travel”. This data will not be associated with specific users and will be collected using OHTTP to remove IP addresses as potentially identifying metadata. No profiling will be performed, and no data will be shared with third parties. (read more)
The Copy Without Site Tracking option can now remove parameters from nested URLs. It also includes expanded support for blocking over 300 tracking parameters from copied links, including those from major shopping websites. Keep those trackers away when sharing links!
Why would they need to tie that telemetry to people in order to use it to inform their own development (as it states as the purpose, and is the purpose of all their telemetry as far as I know).
They are specifically not tying it to people, but to countries.
