His definition of "us" seems to just be "Americans". Which is fine because he's talking about American companies...

The assumption is that Russia, China, Iran are less dependent on Google, Twitter, etc., in part because some of them aren't allowed to operate in those countries, in part because some of them are much less dominant in those markets. 'Us' means 'people who might care that Twitter (or whoever) is down'.

Google, Twitter, Reddit, Facebook, etc, all legally operate in Russia.

But most have regional replacements. WeChat in China, VK (and some Telegram, though it's now blocked?) in Russia. This makes them less reliant on the American originals, which is why governments often encourage home-grown knock-offs.

Yes I have been also hit by the same bad feeling. Thanks for pointing it out.
