We need to be open by default. We should be trying to make close more palatable by sprinkling a little open sauce on it. We should focus on principle: open first, and then, if necessary, spike it sparingly and temporarily with a bit of closed, but keep the preponderance open to make sure you don't capitulate to the dark side. Open just tastes better.
Ugh - that should be "we shouldn't be trying to make closed more palatable by sprinkling a little "open" sauce on it." I'm thinking things like the Linux subsystem in Windows 10 <- exactly the *wrong* direction to be heading.
