I worked at Mouser as a developer for a few years, the real reason is because our parts are used by terrorists, etc. to build weapons that kill people/bombs.

We created a service that blocks people from buying various parts using a ton of different complex business rules (one simple rule we had was we straight up didn't sell ANYTHING to the middle east for a while).

Startups were another business we didn't sell to simply because of the sheer amount of fake companies we got trying to work around our rules engine.

Alot of the rules for our service was mandated from the FBI. That was a fun call to reveive from them.
