But OP's link, https://www.math.brown.edu/streil/papers/LADW/LADW.html does not redirect. So it seems like a problem that the site owner can fix.

As in, if you didn't know a second newer version existed, would you find it? Certainly the new version should prioritize the older version.
FWIW, my query "Linear Algebra Done Wrong" yields the newer version (2017), but I've just interpreted OP's point as being illustrative and helpful to readers (and it looks like the link now does point towards the new version. Possibly this made my query work)
