Concise Word/Concept for: "Deceiving with a GOOD reason, to hide their REAL reason" [duplicate]

Is there a concept/technical word in law, politics, psychology, literature (e.g. George Orwell), signalling theory etc for the following deceptive technique, process or phenomena:

The act of avowing that something is motivated by:

A good reason

But it is actually for a:

Hidden, less noble, reason

The deception functions this way: the avowed reason acts as a cover-story for the true-but-concealed reason.

I’ll give a political-revolutionary example:

Avowed: We are doing this for the people

Real: We are doing this to establish a dictatorship

And a political commentator could say:

The revolutionaries are _________ {NAME OF DECEPTIVE TECHNIQUE, PROCESS OR PHENOMENA}

The revolutionaries are using _________ {NAME OF DECEPTIVE TECHNIQUE, PROCESS OR PHENOMENA}

Here are a bunch of examples of other psychological methods that would fit the empty slots:

• The revolutionaries are Love bombing
• The revolutionaries are Nudging
• The revolutionaries are Low-balling
• The revolutionaries are Fearmongering
• The revolutionaries are Baiting-and-switching
• The revolutionaries are Gaslighting
• The revolutionaries are Virtue-signalling

• The revolutionaries are using Doublethink
• The revolutionaries are using Grey Propoganda
• The revolutionaries are using Bribery
• The revolutionaries are using Ingratiation
• The revolutionaries are using Superficial sympathy
• The revolutionaries are using Character assassination
• The revolutionaries are using Emotional blackmail
• The revolutionaries are using Intimidation
• The revolutionaries are using Nit-picking criticism

I'm trying to avoid nouns that require an article prefixed, e.g.

• The revolutionaries are using a gambit
• The revolutionaries are using a ruse
• The revolutionaries are using a pretext
• The revolutionaries are using a trojan horse
• The revolutionaries are using a trick

Ideally, I am looking for:

• a verb ,or

• a noun (that doesn't require an article)

The word (if there is one) might resemble the form of some of these "Ericism": https://theportal.wiki/wiki/Ericisms

or

https://en.wikipedia.org/wiki/Category:Deception

My question is not this: What is another word for a reason that is "not the real reason"?

I think a concise word/concept to express this specific kind of two-sided deception would be very useful!

Thanks for reading

I wonder why you rejected pretext. I can't think of anything that better maps to your description.

pretext
_NOUN

A reason given in justification of a course of action that is not the real reason.

Here are some examples given:

_{‘The buzz is that the political agenda of the Minister's visit was merely a pretext.’}

_{‘Of course, there are always good pretexts to postpone political reform.’}

_{‘He has often sought to justify repression on the pretexts of threatened coups against his government.’}

_{‘We're the ones who unquestioningly march behind bullies into other countries on fictitious pretexts.’}
