Isn’t Debbie Fields Jewish??
I found a reference she made to having a Jewish mother-in-law. So it may be that she comes from a mixed family, and as a result of becoming aware that America does indeed house a number of different religions that celebrate different holidays, she might see value in being all-inclusive with her products.
She sold the business years ago after running it into the ground.
No different than Famous Amos. Just a name, the founder doing something else.
