AWS does it more efficiently; it takes down many startups at a time when us-east-1 goes down.

I remember a Workspaces outage about 5 or 6 years ago, and the problem for us was that the redirect link in the console had US East 1 in it.
The workspaces themselves weren't in US East 1 and nothing relied on US East 1.
Emailing users who needed it an alternative link with a different region in the URL for the login redirect fixed it for us.
I know some workloads help to be colocated but all these places are connected by fiber and every cloud has a worldwide CDN it seems.
It's one of the oldest and largest regions. It hosts the most services, both low-level platform stuff and higher level managed services (which run on the low-level platform stuff), so services tend to be more performant.
Geographic location is also good.
Also, due to scale their pricing ends up being cheaper.
Let's say that it's the region people use by default, unless they have a compelling reason to have a presence in any other particular region.
