> No one is going to not buy something because it is kosher. But if paying a thousand dollars a year to put a small circle-u symbol on the back of your box can increase sales by 1% among observant Jews, most companies are going to do it.

Contrary to perceived politics, many Muslims will eat kosher food because it's a superset of halal rules (excl. alcohol).

It's a globally consolidated certification through organizations like the Orthodox Union. This is unlike halal which is local and has many scammers offering to pencil whip compliance. This means many Muslims will prefer kosher to "halal" food to avoid due diligence on the certification agency.

To tie this into age-verification, companies and ecosystems will use the strictest method that makes them globally compliant. Consumers will prefer that convenience even in the presence of intense political beliefs.

A bank that uses seamless OS-level age checks everywhere will win against one asking manually in the jurisdictions it isn't required.
