This seems like poor branding on the part of the cigar brands (at least for online sales).

One of the Bacardi family was locked up / exiled during the first Cuban revolution ironically.
So, no, "I Can't Believe It's Not Butter!" is not a bad brand for margarine, but saying "Cuban" something in a cigar which causes all manner of embargo difficulties is bad branding.
