A conspiracy would be organised and proactive...
Opportunism is reactive, and it was, here, an opportunistic motive.
The timeline is:
The 7th of March, German Armies enter in Rhineland.
The 8th of March, the French council of ministers, albeit it was indeed divided, order a partial mobilization of the army, with the aim of a military action in Rhineland. IIRC, Sarraut, the president of the French Council ordered to Gamelin, the head of French High Command to immediately expel Germans troops out Rhineland... and Gamelin refused to obey to the government... It is as simple as that.
There were strong factious feelings within the army and especially the High Command, feed by defeatism, obviously, but also by anti-republicanism and anti-parliamentarism (and, paradoxically, by Anglophobia).
So, facing this refusal of the high command, and, informed by the High Command that there were many more German Forces in the Rhineland than in reality, and the army refusing to act. The divided council, now facing the insubordination of the High Command, lost its willingness, was dominated by "doves" and seek British and Italian support, like you describe it.
But it have to be added that the watchword of the right-wing politically close to Pétain and many others generals, at the time of the re-militarization of Rhineland was: "No Jewish Crusade [against Germany]" or "We'll not fight for Jewish". That also enlighten how Hitler's threat was perceived, and indeed it seem it wasn't what appeared to be the main threat in High Command's mind. A defeat would be a blessing in disguise and they indeed lauded the defeat as a divine providence.
On the Rhineland, as I understand it, Gamelin basically said that if the French Government wanted to oppose it and invade Germany, they would need a full mobilization (in case it led to a full-blown war with Germany). This was less politically and economically viable to the caretaker French government than if he had said they could succeed with just their standing forces on the Maginot, but hardly represents defying his political masters. He was not aware of how much of a bluff the remilitarizatuon was or that Germany was prepared to back down. In fact, as I understand it, he believed more of the German Army was in the vicinity than Germany had public ally claimed (surprisingly, the Germans were telling the truth about only sending token forces into the Rhineland). French intelligence also counted paramilitary and militarized police units in the Rhineland. While they Obviously weren’t as well trained or equipped as the German Army and portraying them as such was misleading, completely discounting them in considering a possible war situation would have been a mistake.
Once the decision was made not to intervene, the French government did its best to blame its Locarno allies by basically saying it was ready to intervene as soon as Britain and Italy were, and then offering to “back down” in exchange for closer Franco-British planning and cooperation.
More broadly, while high command defeatism/willingness to collaborate certainly played a role in events once France was defeated in Europe, I still struggle to see how it was the cause for said defeat. The French military and its leadership did perform poorly, but it’s hard to say they weren’t trying to win because they preferred a German victory, at least until said German victory in continental France had already happened.
