Comment (by DJPaul):

 Looking at the new function, I'm not sure the name "permalink access" is
 correct -- it's not specifically dealing with the permalink. Perhaps
 something like `bp_activity_user_can_read()`? That way  Maybe
 @boonebgorges has an idea.

 What do you think about moving the "If activity is from a group, do an
 extra cap check" underneath "If activity author match user, allow access
 as well", and add a check - e.g. `if ( ! $retval && bp_is_active( 'groups'
 ) && $activity->component === $bp->groups->id ) {` -- I'm not sure if `
 $retval = $group->user_has_access; ` could ever be false and thus prevent
 a `true` we explicitly set earlier, but this would avoid that.

 And finally for the PHPDoc throughout, `$activity` is probably of type
 `BP_Activity_Activity` so we can use that to describe it instead of the
 more general `object`.
