No, it doesn't, because “affordable” doesn't mean “subsidized”, it means the purchase or rental cost is (and, usually when it comes to rental-committed units in a development plan, is guaranteed by contract or some other binding arrangement to remain) within the U.S. Department of Housing and Urban Development’s income-based affordability guidelines for a specified income level; in the case of the plan under discussion, that income level being 50% of the Areawide Median Income for Santa Clara County.
Very little Bay Area housing meets this criteria.
The media accounts drop the reference to the income-based affordability formula from HUD and the income level in the plan to which the formula is applied, but that isn't a problem with the term, it's a problem, if anything, with the media accounts.
