And of course the "knowledge" part - the entropy being a function of the probability distribution for the microstate conditional on the macrostate - is there just the same in the microstate counting approach. (Where the latter is applicable!)

If given the macrostate all microstates are equally probable we can just count them. The more there are the higher the entropy.

In general we have a probability distribution for microstates conditional on the macrostate. To have a clear understanding of entropy that should be at least mentioned.
