Mold linker may not switch to a source-available license

Require all requestors to identify themselves as individual open source hobbyist or closed source commercial.
Refuse the closed/commercial work unless they make a monetary contribution.
The (A)GPL is a source code copyright. It doesn't force you to fix anyone's problem or even interact with them.
If the requestor is a business, it'll be an undesirable development burden to carry their own fork with their own patches. It probably makes business sense to pay instead of hiring their own compiler developer.
Might not make for the best community interaction though.
That's assuming the courts agree. I haven't read the linker code, but it's very possible that whatever code the linker includes would not be found "creative" enough to be copyrightable. In contrast, libgcc, which gcc links into generated binaries, contains non-trivial routines[0].

I really don't think that is the point. This seem to be targeted at scaring legal departments to ease over the process of having corps fork over the money for something they might think could be obtained for free.
