For what reason have governments and media omitted test-positivity rates for COVID?

During the COVID situation for the last year and a half, governments have setup PCR testing programmes for SARS-CoV-2 detection in individuals. As time went on, many governments have seemed to move away from death and hospitalisation figures but instead put their focus into what they call "COVID cases". These are the total number of PCR tests for SARS-CoV-2 that have come back positive for a given day. These are absolute figures and in my eyes are therefore completely valueless without the total number of tests are reported alongside them. For example

"The UK has reported 27,000 cases in one day for the first time since..."

What value does this provide to the viewer/listener when it could simply be the case the total number of people tested that day has increased?

I've noticed this trend across multiple countries. Media outlets are showing graphs of "cases" without ever providing the total number of tests that have been carried out that day. Many times when the "cases" graphs are superimposed onto test-positivity graphs of the same country, you get a much less bleak picture. The data in almost all countries is made available but never broadcast to the masses, instead you have to go out of your way to look for the specific web page and select specific options in order to get the desired graph on your screen.

Mathematically speaking this does not make sense, so my question is, why have so many governments/media outlets failed to use test positivity over mere "case" data?
