I can state an opinion about what should be the case without always qualifying it by saying something like others may disagree, etc.  This sort of thing is done constantly.  See editorial pages and opinion columns for innumerable examples.  When I write in such a way, I assume that it is generally understood that I am expressing an opinion.

This is not a question of taste, usual or not.  It isn't a question of I like chocolate ice cream.  It is a question of which better serves users. 

Aside from that, Openbook does not automatically save settings.  Window-eyes didn't.  I don't think Kurzweil does. These designers may have had good reasons for what they did. 

In the case of Window-eyes, the reason was so that users could experiment with settings, then not accidentally have them be saved.  I suspect that also, in the cases of all three of these programs, this was done so users could change settings, then change them back if the changes were intended to be temporary such as temporarily changing a contrast setting.  It was evidently intended that these settings would not be accidentally saved on exit.
