According to wikipedia, 洪門(Hongmen) is the alternative name for Tiandihui(天地會), an illegal society in Hong Kong, which sounds similar to Hongmeng.

Ah, so "black societies" meant something like "criminal organisations", maybe triads? I thought to begin with the comment meant dark-skinned people.

So, if I have it right:

Originally Huawei called their OS 'Hongmeng'. But that sounds like 'Hongmen' which is an alternative name used (but not exclusively) for the outlawed Tiandihui crime syndicate.

something close to that.
