"Open" is a great marketing term to signify to geeks that you're hip to the whole movement thing, and "Wall" of course is a classic Cybersecurity term that is an instantly recognizable part of "firewall", but when you make a portmanteau into "OpenWall" and a big gaping security hole is revealed, surely the irony is not lost on us.
OpenWall is a highly-respected security research and hacking project from the early 2000s. This group was responsible for revealing numerous 0days during the chaotic days of the early Web, as well as developing exploit mitigation techniques. These days it's mainly known for hosting security-related mailing lists such as oss-security and kernel-hardening, widely read by security researchers and kernel developers.
The name is more than appropriate. It's not the developer of Mozilla VPN.
