Is there any reason why there is no large generalist Lemmy instance managed from the USA? Is this just a coincidence?

Thinking about this lately, especially in the context of the UD elections getting discussed a lot all over Lemmy.

If you look at the top 20 instances https://fedidb.org/software/lemmy

• Lemmy.world and feddit.nl are Dutch
• Lemm.ee is Estonian
• Feddit.org, discuss.tchncs.de are German
• SJW and lemmy.ca are Canadian
• Lemmy.blahaj.zone, aussie.zone and Reddthat are Australian
• sopuli.xyz is Finnish
• slrpnk.net is Portuguese
• lemmy.dbzer0, infosec.pub, mander.xyz, programming.dev, lemmy.sdf.org are thematic
• Beehaw is USA-based, but defederated from LW and SJW and still on 0.18.3, so not sure they're even that interested in Lemmy anymore

Out of the top 20, there is Midwest.social and Lemmy.today but they are quite small (326 and 201 monthly active users).

On the other hand, a lot of other countries have their own instances

• feddit.uk
• jlai.lu
• feddit.dk
• szmer.info
• lemmy.eco.br
• feddit.cl
• feddit.it

With the USA population and the Internet presence of the USA citizens, you would expect at least one large generalist instance based in the USA, but it doesn't seem to be the case.

Any ideas what the reasons might be? Is this just a coincidence?

The website and the agreement will be governed by and construed per the laws of the following countries and/or states:
