You keep posting these thoughts with very little input of your own for direction. What exactly are you asking?
There is freeware and there is shareware. Freeware is always to be free, shareware is try before you buy. Of course there are jerks that say free and then have nags, ads, viruses, etc.
We have a list of very good freeware
here. These are hand-picked and used by our members. Even so, many include toolbars (often added just to make some money but are unrelated to the product) that you are best to unselect during install; always read carefully before hitting NEXT.
