If you're using "Wahhabi" to describe the movement of Abd al-Wahhab, then it must be limited to the Salafis of the Arabian peninsula who accepted his teachings at that time. But "Salafism" is a much broader term, and most of those movements who identify with it have their origins outside the Arabian Peninsula. For example, in India the Salafi movement commonly referred to as "Wahhabi" by their opponents refer to themselves as the Ahl-i Hadis, and their origins are in northern India.
More broadly speaking, "Wahhabi" has also become a term of abuse. For example, Ahmed Raza Khan Barelvi routinely referred to his Deobandi opponents as "Wahhabis", and he himself was also accused of being a Wahhabi. Even on the Cafe I have seen Erdogan called a Wahhabi.
I really don't understand what you mean by "version of events" in this context.
