Islamic Workers' Monetary Compensation Forbidden or Allowed?

Some claim that monetary compensations of those working for Islamic causes is not allowed. According to the following Aayah, apparently, even the workers over sadaqaat can be compensated from the same sadaqaat. Similarly, the category "in the Way of ALLAH" cannot be restricted to fighting in the Way of ALLAH only, and can include the many types of struggles in the Way of ALLAH. e.g. research for proper understanding of Islam, to counter the wrong translations, to counter the misconceptions, for deeper and more accurate understanding of Islam etc., may also be included. Spreading and promoting Islam as far and wide, and eventually even fighting for ALLAH, are all struggles in the Way of ALLAH. All of this, is time consuming. Some demand that those struggling in this path must somehow never take funding, and make a living, while being restricted to worldly jobs only, then give the time for their responsibilities, and still somehow manage to do all this time-consuming work part-time as a hobby. They may make a good site using coding and by using the already available data, but may never understand, that this thing they have done is only a small part of what must be done to solve the problems faced by Muslims, which cannot be solved using such hobby style activities only, and by them being quick to boycott or doubt people taking the funding route instead of collaborating with and respecting such people, some of whom had even risked their careers by not building their worldly careers to invincible levels and had spent the free time building their skills for Islamic causes.
