Filipino is an evolving language. (Tagalog too.) The KWF is neither powerful nor influential enough to change the way we learn and re-learn Filipino, so I don't mind what they say so much, unless of course you're an academic or a researcher. They once told us (high school students) to differentiate between "nang" and "ng," then a few years later (university), changed their minds to say to just spell both as "ng."
