No, they really just forgot the characters. I lived in Japan for the better part of a decade and it isn't at all uncommon. There were many times when I explicitly asked natives to recognize or help me with a Kanji and they struggled as well. I doubt everyone's been systematically lying when you genuinely ask for help. The reason is just digital input really. Pinyin and Romaji typing have become so common that a lot of people write Hanzi/Kanji by hand less and less and it's so complicated of a skill there's really no other way to get it in your brain other than practice. I even notice it myself, I easily recognize 10x more characters than I can accurately write.
