The ACM is a quite large organization, with tens of thousands of paying members (like myself, for >25 years). They also take part in organizing conferences. Have you heard about the Turing award, often equated to "the Nobel prize of computing"? It's the ACM that awards it.
There are many other sources of income for the ACM. they have surely run the numbers and realized that, while not negligible, the income they got from individual access to magazine articles was not relevant enough.
I guess this will not affect too much their magazines' and journals' subscriptions. Some of the ACM's magazines, such as CACM (for the whole membership of ACM) and XRDS (for student members) are covered by membership fees; the journals, which are way more specialized and way more expensive, are often paid by university libraries, and I suppose that will not change with their shift to an OA publishing model.
