You avoid using it, or avoid using third party code that uses it?

The latter makes sense. The former does not, as you can relicense any time you want.

Only if you are the sole copyright holder, i.e. no (nontrivial) external contributions.

Which is why I avoid it directly, unless I'm not touching the code at all. If I'm just using it as-is, then I don't care.
