Kudos to the QUIC working group for this absolutely correct response: "We won’t hold any further interim meetings in the US, until there’s a change in this situation."

International conferences should be considering this also. I'm a plain white guy with nothing dramatic to hide and I was apprehensive on my recent visit to the US. I can imagine people working in tech security, or with backgrounds/family from particular countries, would be more nervous.

I work in tech security and indeed, I've thought about this topic and I'd be nervous as hell.

Then again, needing to put my laptop in check-in luggage (with a backdoored lock? Is that really a thing? I only saw "TSA-approved locks" mentioned somewhere and am only inferring the existence of backdoored locks here) is a no-go in the first place, so I'd need to (1) want to go to the USA, (2) not take a laptop and (3) probably buy a special backdoored suitcase. That's a pretty rare combination.
