Don't know about other countries, but in the Bay Area a bunch of those billboards have been vandalized/edited by non-Zionist Jewish groups.
Anyway, advertising media are antithetical to debate, which presumes approximately equal access to an audience to lay out two or more competing ideas at once. You can't argue with a billboard, you can only rent another billboard, and pretty soon you have billboards everywhere. This is a garbage concept of political discourse.
