FakeMaven: Daas Noteh addresses the MaHaril on page 140, 141. The questioner quotes it, and Reb Chaim answers in his short written style.He is not ignoring it.
You say “And the best for the last, about nipitz leshma. For anybody that is an Ashkenazi and follows the Rema, המנהג להקל בניפוץ, (O”C 11) . I therefore do not have the audacity to say that for us nipitz is nothing more than a chumra.” BUT YOU LEAVE OUT THE MISHNA BERURA who quotes the Pri Migadim b’shem Maharal that one should be machmir l’chatchila.
As for Krias Shema, nice quote from the Shulchan Aruch HaRav, but the M.B. is not machria and is not willing to be meikel like the Shulchan Aruch Harav, and it is a safek d’oraissah.
And what you write “It’s very well known Rav Elyashiv spent his time on Shas and Poskim and was generally not the kind of posek who researched the technical aspects the Shailos — that is something Poskim the like Rav Belsky do. Instead, Rav Elyashiv’s approach was to respond precisely to the question how it was asked”
AFAR L”PUMAY!! That is right out kefirah and disrespect for a Gadol Hador. It is in total violation of our Mesorah and Trust in our Gedolim and Poskim. Reb Elyashiv understood the Murex, the MaHaril, and all relevant Rishonim and facts much better than you or any other blogger. To write him off like that is grounds for some serious stuff. As the Rambam writes: אע”פ שהמבזה את החכמים אין לו חלק לעוה”ב אם באו עדים שבזהו אפילו בדברים חייב נידוי ומנדין אותו בית דין ברבים וקונסין אותו ליטרא זהב בכ”מ ונותנין אותה לחכם והמבזה את החכם בדברים אפילו לאחר מיתה מנדין אותו בית דין
