I believe the popularity of the sign lies in its ambiguity. You see, the mainstream discourse never went as far as to say "it is not OK to be white." It was hinted at, in a more or less subtle way, through the "white privilege" (some corporations actually have obligatory trainings on this) and in thousands of indirect ways making white people guilty of the skin they were born in.

So for some people the message of that poster was infuriating. You can't openly disagree with the literal meaning, but on the other hand, many people do it internally. They believe that white people as the descendants of slave owners should inherit the collective guilt of their great forefathers (even if it was a family of a third wave of immigrants from Europe that never owned any slaves). The very fact we are even discussing that is telling in itself.
