Just because you 'don't recognize' what has been offered to answer your question, that doesn't mean that the question wasn't answered. Seems to me that you don't want to accept anything that contradicts your preconceived ideas.
You apparently are also judging Napoleon's relationship with all of the Confederation states by his relationship with Westphalia. Westphalia was a Napoleonic creation, as was Berg, but the major states of the Confederation that joined Napoleon in 1805 by choice so as not to be ingested by either Austria or Prussia, were not Napoleonic creations. They were already established independent states with their own ruling houses.
Owen Connelly, in his book Historical Dictionary of Napoleonic France, 1799-1815, describes Westphalia as a 'model state' citing that its constitution, given to it by Napoleon 'proclaimed equality before the law, equality of religions, the dissolution of guilds and similar associations, the abrogation of noble privilege, the abolition of serfdom' and the adoption of the Code Civile. Napoleon's object was to transform the different older German states into a 'modern state' which would be new in Germany, hence my use of the term 'experiment. (pages 506-507 of Connelly's previously mentioned book).
It should be noted that when the United States was given its Constitutioin in 1787-1789, it was termed the 'noble experiment' as a new type of state 'a republic if you can keep it' in Benjamin Franklin's words. Westphalia was also an experiment for states in Germany. That the Westphalian experiment failed is not to say that it wasn't an excellent effort and idea. And the ideas generally survived the dissolution of Westphalia in 1813-1814. Connelly also states that 'In many respects' Westphalia 'served the Prussian reformers as an example; many of its modern institutions were copied by other states of the Confederation of the Rhine and some of the successor states...allowed reform legislation of the royal Westphalian era to remain in effect.' And this included, surprisingly, Prussia.
