Because the boinc group does not need access to most of those files.

The BOINC client just provides the slot and the "shared" folder to exchange data with the task.
Anything else within the slot is created and under control of the task owner (boinc user).
In addition the task runs within a container namespace which does additional mapping.

Why are files that are in theory slots accessible to boinc group?
I would like to be able to run sudo multitail -Q 10 '/var/lib/boinc/slots/2/**/athenaMP-workers-EVNTtoHITS-sim/**/AthenaMP.log' without sudo.
i am able to run tail -F /var/lib/boinc/slots/2/cernvm/shared/runRivet.log without sudo after i added my user to boinc group.
