There's a fair few FOSS projects that have a bus factor of 1 or 2, it's one of the things I check these days before considering adoption. That said, having multiple core contributors isn't always a guarantee either if they're from the same company, that's another bus factor of 1, especially if the company's core business isn't selling software to others, they'll usually end up neglected or abandoned. Great examples are Robinhood's Faust library, and Shopify's stewardship (or lack thereof) of Sarama. Not their core business, so eventually, the devs get moved on to stuff that makes money directly.
