Same here, really. That's why I started using it. I'd seen it pop up for a moment on a few sites I'd visited, and it was so quirky and completely not disruptive that I didn't mind routing my legit users through it.

So maybe there are more people who like the “anime catgirl” than there are who think it’s weird

*anime jackalgirl ;-)

Quite possibly. Or, in my case, I think it's more quirky and fun than weird. It's non-zero amounts of weird, sure, but far below my threshold of troublesome. I probably wouldn't put my business behind it. I'm A-OK with using it on personal and hobby projects.

Frankly, anyone so delicate that they freak out at the utterly anodyne imagery is someone I don't want to deal with in my personal time. I can only abide so much pearl clutching when I'm not getting paid for it.

The Digital Research Alliance of Canada (the main organization unifying and handling all the main HPC compute clusters in Canada) now uses Anubis for their wiki. Granted this is not a business, but still!

For what its worth, I think that a UN/(Unicef?) website (not sure which one) did use anubis so maybe you can put it behind businesses too :)
