I guess it's been a while, but using µ in a name isn't exactly unprecedented, μTorrent was the BitTorrent software to use at the time, and so that discussion played out then. Everyone just called it uTorrent because it was the easier thing to type and made the pronunciation obvious and singular.

Until just now I would have sworn uBlockOrigin used μ. It's the first thing I've installed after the OS since it existed, but your lack of mentioning it made me check.
