They started as an Illustrator clone, than moved to copy Sketch functionality.

I have witnessed the demise of my favorite tool Fireworks in the hands of Adobe. In one point in time we used Inkscape which is working with SVG by default. I can open my designs from 2008 without any problem.

Let's hope that after this fiasco the solution will finally emerge.
