iPhone being banned in the Netherlands?

Yes, it is. More or less. There is a new law in the Netherlands that forbids the sale of (electronic) devices containing batteries that can not easily be removed for disposal. The regulation is there to prevent polluting batteries ending op in the regular trash. The regulation also stipulates the requirement of describing how to remove the the battery in the manual. The iPhone fails both regulation demands. The regulation is based on a European directive. No doubt more European countries will follow suit.

Already imported volumes may still be sold. However since the 26th of September it is no longer allowed to import that kind of electronics. Exceptions exist however, i.e. for medical equipment and children toys. Logically no one desires to see a baby sucking/shortcircuiting a lithium-ion battery. Particular faulty ones that might burst into flames.
