Inkscape is fantastic. It, Blender and Krita has completely freed me from paying subscription fees for creative tools. I used to be an Adobe Suite (PS, AI, AE, PP) user, but I've yet to encounter a situation where I've felt limited by not having access to those "premium" applications any more. There are issues of course - memory leaks and odd GUI handling on Windows in particular - but I've had the same sort of issue…
I don't disagree with most of what you're saying, but I wish there was a decent open-source 2d Vector animation software that could compete with Flash/Animate. I know Krita has a decent animation tool, but it's only raster, and I haven't encountered a really good vector tool yet.
I've been building out some backend stuff lately so there's a bunch of new features waiting to go in. https://github.com/Logicalshift/flo_draw has some demonstrations of the sort of procedural animation features I'm planning on adding, for instance.
