Tofu has an ancient reputation as a vegetarian replacement for meat. Its taste depends on the preparation (raw Tofu is very flexible).

Some people associate it positively ('ethical', 'wholesome', 'tasty'), others do not ('not the real thing', 'tasteless').

In its original producing country it's often used as an expression of excessive softness ("tofu mental" for instance, for mental fragility). But it's also cute and inoffensive, I think it's a nice name overall.

I think OpenTofu should embrace the negative connotations. Go crazy, make everything Tofu, that's the goal. It'd be a nice side history for marketing purposes. I doubt anyone would not use the tool because of it and others would get a good chuckle.
