Wind of Change

Let's look at the statistics for the games, where the control was taken – from a scroll (when the building is at a certain level), from a guild (including companies), from Pandora, from the Grail (including companies), from a relic, or from Utopia (possibly also from a scholar, although this is rare)?

I don't like being told "let's," but I'll try to answer. I don't keep statistics; I judge by the final result. If all of the above were sufficient for a balanced (from the perspective of playing Heroes) acquisition of control, then neither in SoD nor in HotA would the restructuring option have appeared. But it does exist. Moreover, almost no one uses the option to disable restructuring in SoD, even those who strongly opposed its introduction.

Why doesn't this factor prevent Moretti and Gomunguls from winning? (by the way, you deliberately omitted this thesis?).

I didn't just omit this thesis of yours; I also omitted many others, and I explained why – all of this has already been discussed many times.
Specifically regarding this thesis, if you insist. Even if we were playing the original SoD without any rules, someone would win more often. Perhaps it would be Gomunguls and Moretti. It is very likely that they would be satisfied with such a game, such is their nature. But in reality, we are playing a SoD that is far from the original, we are playing with rules, and sometimes we change them, and there are reasons for this. And if we change something again, then we can safely assume that Gomunguls and Moretti will again be satisfied, since they are willing to play with what exists.
This does not mean that those who see the possibility and desire to make improvements to the game (as has been done many times) are wrong, and Gomunguls and Moretti will most likely enjoy using these improvements.

To put it more briefly, perhaps this will be clearer. In any game, with any rules, at some point, someone wins more often. And opponents of making changes can use your thesis: "Players A and B are winning, nothing bothers them, so there is no need to change anything." But in reality, all games change from time to time, which means that this thesis is untenable.
