The other countries might not place tariffs on tech company products but they can damage these companies in other ways.

I believe the European Union actually has a specific type of anti-tariff policy that they could implement that would eliminate intellectual property protections of software or entertainment companies from countries engaging in trade wars. It’s an option of last resort and I don’t think the EU would actually implement it in response to the Trump stuff but if they did it could be devastating for Silicon Valley and also for Hollywood.
