He had it coming, some party loyalists remarked.
Did he really?
Others, on the other side of the fence, felt that Muhyiddin was just saying it as it is.
And there were others who thought it was just a show because, for heaven's sake, Muhyiddin would never do Najib in.
Muhyiddin's remarks when officiating the Cheras Umno division meeting Sunday night had been met with shock, ire, despair, relief, excitement, encouragement from people - depending on where you stand in all this 1MDB- PM saga.
It created a raging buzz in and out of social media and cyberspace.
If you had been following all this -- and if you didn't, two things; either you are just so fed up or you are living in a cave - you'd know that it gets more murky and baffling and how much more, remains to be seen
After Muhyiddin's remarks were made so public, people were all speculating that he'd be sacked.
Because 1) it showed that he is not with the PM on all this and was only making things worse for the PM and 2) man, has he got balls to say all those things.
Of course, going by convention, decency and all that - Muhyiddin should not have said all that - according to some party loyalists.
They say that Muhydidin, of all people, the number 2, should not feign ignorance, a confused mind, lack of understanding. It was bad enough that former PM and party president Tun Dr Mahathir Mohamad led the chorus of fierce attacks against Najib and now his own deputy.
That is the job of the opposition.

But really, if you followed what he said, he did not say anything damning. If he was not able to to understand the 1MDB controversy, well, that is really his problem.
He mentioned Deputy Finance Minister 2 Datuk Husni Hanadzlah and Urban Wellbeing, Housing and Local Government Minister Datuk Abdul Rahman Dahlan having explained the issue to their colleagues but had still left him in the dark. Which is odd because Rahman, it seems, did a good job of explaining it.
Meanwhile, Tan Sri Gani Patail has had his services terminated on health grounds effective yesterday. He is replaced by federal court judge Tan Sri Mohamed Apandi Ali.
Asked to confirm this, Gani said he did not resign but "they terminated" his services.
Gani is leading the task force investigating allegations against 1MDB. It looks like he no longer is.
Others in the team are Bank Negara governor Tan Sri Zeti Aziz, Inspector-General of Police Tan Sri Khalid Abu Bakar and Malaysian Anti-Corruption Commission chief Tan Sri Abu Kassim Mohamed.
Now, this is all going to be an explosive subject for speculation.
Gani has about 2 months more before retirement, I believe. So the questions people are asking -- why -- does Gani know something and about to do something? Is he really not well? And, of course, the task force is now under scrutiny.
Gani, it seems, needs dialysis treatment but is not a diabetic.
Meanwhile PM Najib explains the reason for dropping Muhyiddin which he said was a tough decision for him but he needed the Cabinet to be united.
I can accept difference of opinion but as a cabinet member one cannot do it in a public forum as it can create public misconception. This also affect the concept of collective responsibility,” he said when announcing the new Cabinet line-up here on Tuesday.
Najib added that the reshuffle was also to strengthen the lineup before the 14th general election.
He said the decision to go ahead with the reshuffle took into account the political scenario and was in the best interest of the administration.
“This ensures that my administration remains committed and focused on development as promised by the Barisan Nasional government in the last general election,” he said in his speech.
He added that the Cabinet should act as a team under all circumstances. - The StarUmno vice-president and Home Minister Datuk Seri Ahmad Zahid Hamidi replaces Muhyiddin as DPM. Muhyiddin who also lost his Education portfolio is replaced by Datuk Seri Mahadhir Khalid.
Muhyiddin, in an immediate response to his sacking, said he accepted the PM's decision to drop him from the Cabinet and thanked him for the opportunity to serve the government. He also said he will remain loyal to Umno.
"Kecuali dalam isu 1MDB, saya mempunyai prinsip dan pendirian saya sendiri dalam mempertahankan hak rakyat, namai baik parti dan kepentingan negara. Jika kerana pendirian saya dalam isu ini menyebabkan saya digugurkan daripada kabinet maka saya redha.
Saya akan sentiasa setia kepada perjuangan UMNO. Sebagai Timbalan Presiden UMNO, saya akan terus melaksanakan amanah yang telah dipertanggungjawabkan kepada saya dan mencurahkan khidmat bakti saya demi memperkukuhkan parti serta mengembalikan keyakinan orang Melayu dan rakyat kepada UMNO.
Kepada Allah saya berserah."
From now, my friends, it's Que Sera Sera.
