Well, I just did a backup and was gratified to see that my Russian-language filenames (e.g. Так что же нам делать?, Л.Н.Толстой) were echoed in UTF8. It was my first use of this utility, and I'm very, very impressed by its speed and power.
My field of practice before I retired was software human factors and, while I agree with you that this utility has an unusual and not especially intuitive interface, I didn't find it difficult to puzzle my way past the differences. Of course, my thirty years' engineering experience might have something to do with that; I'm sure it would feel more daunting to someone inexperienced.
But I think you have to admit that the base price is more than right: you need neither use it nor pay to find out you don't want to.
Are you perhaps not a native speaker of English? What you wrote seemed loaded with arrogance and hostility to me, and I'm sure you noticed that others here didn't seem to like it much, either. I'd prefer to think that's not the impression you intended to convey.
