Well, they do make some interesting points (Ven Nanananda much more than Ven Nanavira, in my view) but as far as I'm concerned, it's a matter of taste whose particular interpretations you find useful... It's not as if any commentators can prove
that their interpretation is the only possible one.
But perhaps we should get back to the topic. I guess one interesting question is whether the blame for the (alleged) misguided emphasis on "merit making" really originates from misleading statements in the Commentaries, or whether it is from ignorance of the Dhamma on the part of the merit makers.
