It’s not just the domain squatters. They have to find a name they can get with Twitter, YouTube, Instagram, TikTok, Facebook, etc in addition to the domain.

A lot of these are puns/vague money sounding names in different languages.

Wero has got to be the worst of the bunch, though. An awkward combination of "we" and "euro" combined with "vero". At least the other pooq/wolo/snivum/rumio like names aren't trying to hard.

I don't think it explains the "cat walks on keyboard" brand names for cheap Chinese goods on Amazon.

Every single 3 and 4 letter .com domain has been registered for at least 20 years, not a single one is available to register. Domains aren’t the reason for names like “wiro” and “tubi”.
