I look at it as a trade-off between short-term freedom and long-term freedom.

BSD gives more short-term freedom. GPL trades some short-term freedom to attempt to better preserve long-term freedom.

To me that trade is a reasonable strategy, but I also think BSD has a hidden(?) benefit on a different front in the battle for openness. If you have a libre implementation of something but nobody uses it, it's not much use. If the availability of BSD-licensed code induces a corporation to use that instead of developing their own proprietary technology, it might be a net win, especially if that big corporation has a lot of influence over users.

What we want here are more users of the AV1 codec. As such, an implementation that doesn't suck that anyone can use and MIGHT want to contribute fixes/optimizations upstream so they don't have to carry them on their own is a more of a net win than trying to use a specific implementation of that decoder library as a club to open up other software that happens to use it.
