Conversion to indirect reported speech not a matter of grammatical rule
There is a second respect in which we must beware of being misled by the traditonal account associating backshift with indirect reported speech. Converting into indirect reprted speech, however, is not a matter of applying
rules of grammar that are specific to this purpose.
{JTT: emphasis NOT mine}
When I make an indirect report of [Jill's] speech, I purport to give the content of what she said - as opposed to quoting the actual wording,
This is how backshift is to be interpreted, not as converting one tense into another.
6.2.2 Obligatory vs optional backshifting
A backshifted preterite may be pragmatically equivalent to a present tense
Very often, the use of a backshifted preterite is optional.
Factors affecting choice between backshifted and non-backshifted versions

{JTT: the following specifically addresses Paco's concern about the passive though I must admit I'm lost as to why he thinks the passive should be treated in a different manner than other voices.}
(e) Simplification
In [some] case

, the non-backshifted version may be prefered precisely for its greater simplicity.
Consider:
[32]
i She asked me where I was / had been born.

cannot be interpreted as a backshifted preterite: it can be assumed that she did not ask, "Where are you born?"
=================================
The Grammar Book: An ESL/EFL Teacher's Course
The direct-to-indirect speech tense shift is the main piece of evidence cited to support the assignment of tense to modals. However, we demonstrate in Chapter 33, which deals with indirect speech, that the so-called rules of tesne shifting are NOT always followed by native speakers. This is especially true for modals; thus such evidence is somewaht weak.

JTT: Paco, you should have listened to Eladio when he said,
"It was my feeling because I hear people talking in streets and I pay a lot of attention to them (to learn), and I hear many times they were talking about passive without changing it. Now I understand one more time, people talk as they wish and not always following correct grammar rules."
People who use language are the ones who determine its usage. Eladio only made one small slip up and that is understandable for everyone has long been subjected to the old lie that prescriptive grammar is somehow correct grammar. This is false false false.
People determine the rules of language. These old pedants who abandoned thinking in favor of rote memorization of prescriptions have, for too long, misled people on language. For ENLs it didn't and doesn't matter one iota, ENLs have never listened to these old canards.
For ESLs it matters a great deal. So when you, unwittingly I'm sure, pass on another language falsehood, it doesn't help Eladio and it doesn't help others who read the same thing.
