My mother used to judge people on the quality of their cards. She always chose individual cards for family and special friends and was entirely put out if it wasn't reciprocated. I've no idea what was at the root of that, but I always made an effort to choose a lovely card for her, because it made her happy. I think maybe she saw the "quality" of the card as a measure of how the senders felt about her.
I called a halt to us sending card of any type at Christmas between our immediate family some years ago. Why would I send a card to my husband, who lives in the same house as me? It struck me as just something for how. If I want to wish him happy Christmas, I could just say it to him. Same with the offspring/siblings.
I send very few cards these days. One to my cousin, one to mother in law, one to sister in law and family.
To the OP - because of how my mother viewed cards, I can see where you're coming from.
I think some of the responses are a bit harsh. But yes, I think maybe you are over-reacting a bit. Try not to let it upset you, and accept the card in the spirit in which it is sent.
