All of us, at times, have to simplify things in order to be understood. Parents have to simplify things for their young children, which seems to be a major part of the purpose of the Simplified WT.
The college-educated woman apparently recognized that, being very-well educated, she may have had difficulty expressing certain concepts in simple terms. This can hinder rather than help, depending on the person being addressed. Talking over someone's head isn't going to help them, nor is turning them away until they matched her educational level going to help them either. The simple fact is, some people are more educated than others.
I would think that, with more people of low-income, low social status, and people from third-world countries making up the bulk of newer converts, the simplification is necessary and helpful to the jw cause, whether you suspect that cause to be nefarious or not.
