I was going to say, early on, some time in 2001, even MySQL got this
wrong when their website said that for commercial uses of MySQL you
needed to pay for proprietary licenses. Someone then managed to
convince them that was wrong, and they never made such a mistake again
(except an overly eager newly hired and badly trained sales manager
every now and then).
