Google so far has lived up to its commitments to make room in its Privacy Sandbox for rivals, though the UK's Competition and Markets Authority says a number of concerns still have to be addressed before the web giant's ambitious advertising technology gets its blessing.
The Privacy Sandbox is Google's name for a set of advertising-oriented APIs in its Chrome browser designed to be more privacy-preserving than current privacy-trampling web advertising tech – namely third-party HTTP cookies.
For instance, rather than using these third-party cookies to track a netizen's interests and activities, websites can instead query Chrome directly, via a Privacy Sandbox API, for a list of the user's interests – such as news, gardening, and live music – and then show them ads and special offers based on that. This list of topics is generated by the browser from the user's browsing history.
Technically speaking, Privacy Sandbox can be implemented by other browsers, though Apple and Mozilla, to name two, have rejected aspects of the technology for Safari and Firefox – such as the aforementioned Topics API.

Brit watchdog thinks Google's tweaked Privacy Sandbox still isn't cricket
