I&#x27;m sure the Brazilian judge followed Brazilian legal procedures. That&#x27;s the entire point of being a Brazilian judge. There might be other means to achieve a goal but that doesn&#x27;t mean what happened isn&#x27;t legal.<p>In your example, if that German app was targeted to US users (e.g. by localization and marketing) then yes, they should follow US laws. That&#x27;s a test German courts use to determine whether they have jurisdiction in the digital world and I think that&#x27;s fair and should be applied in the other direction as well. If they don&#x27;t want to or can&#x27;t (e.g. by contractual obligations or German law) they shouldn&#x27;t act surprised if the US doesn&#x27;t allow US business to trade with them.
