bcwipe seems to have gone commercial. 1.9-9 is still “free” as in
price, but contains an [incredibly restrictive
license](https://www.jetico.com/linux/bcwipe-help/wu_licen.htm) that
I’m not particularly sure we want to ship given our rejection of
similar situations recently. 1.9-10 onwards, including the latest
1.9-11 release are all “trial” releases which “expire” after 21 days of
use and cost some $35 to continue using.
