Our domain was registered in 2017, and from memory 'Zap' wallet was only launched in 2018. The name 'Zaprite' comes from to 'zap' (pay), 'right' (correctly). Zaprite's name means to 'pay correctly', or, 'pay optimally'. As in, use bitcoin/lightning instead of fiat. We always considered BTC/LN payments as zaps, but just never tried to make it a thing. We see it as very fortunate that 'zap' was actually picked up by the industry.

I actually think it's fortunate. The associations are positive and I personally don't find it confusing (but I've known about zaprite for a couple years now).
