I think it's way too paranoid and impractical to seriously have every single thing homegrown. No Zoom, no Microsoft, no Apple, no Google, no Intel or ARM chips. It's just not going to work. It's not even clear to me that would be more secure. Okay, so you've successfully defended against the threat of the US government pressuring those companies to add backdoors to spy on your conference. Now you have to make sure your homegrown software and hardware in secure. Also the EU is multiple countries with competing interests anyway. Come on. We have to be a little more practical in the real-world I think.
> All of Zoom’s security team is based in the US
That's the point. Thinking that the US are truthful and honest allies of the EU is plain laughable.
