Hi Zorki:
First of all, it’s always better talking with respect to those that give you something for free (that is, no money involved). If you don’t like what is offered to you, just kindly decline the offer and go somewhere else that fulfills your taste or needs.
And maybe if you would have been a little longer here you would have read the post about the new RawTherapee website, where you could have said your opinion before it was even designed.
Nevertheless, it seems that there are a lot of people comfortable with the new design, and I would say even enjoying it. If you don’t like it, but still like RawTherapee, just download the software and keep using it.
No need to be aggressive. I would even say that you tame down your manners or better go away.
P.S.: I like the new website
