There is no industry move to reduce their use. and yet spam remains a problem. the problem will be addressed in one of two ways: either better mechanisms for dealing with spam will be developed, or people will stop using email. (indeed, we're seeing both trends - so it's hard to know which will dominate.) either way, the current use of DNSBLs seems likely to be temporary. what's the justification for carving them in stone, so to speak? given that you seem to accept that they're desirable, why not try to improve them? I'll note that the "industry" does tend to paint itself into a corner from time to time. Sometimes innovation has to come from outside the industry.
