GIMP's mission statement is 1. be hateful to use

It hurts to say but you're right. I was like "can't you remap the right mouse button to another tool? Everything in the context menu is in the Menu bar regardless" and they responded with "nope, design philosophy"

yep. I feel like FOSS projects are always made by code monkeys who have no design sensibilities and designers do not touch any of these. a lot of them are not only unusable but uninstallable by the majority of the intended user base. whenever i find something i want to use it's like:

—cool software. can i double click on an icon and have it ready to use?
—umm, don't be ridiculous, normie. you gotta self host it and use the command line to enter some arcane incantations obviously. alternatively you can use these other methods you've never heard of. if you need any help you can refer to their respective indecipherable documentation.
—ok I'll keep what i have until i find something that's made for regular human beings, thanks.

Martin Owens is working on CMYK support for Inkscape as we speak, and Gimp releases v3 during the summer if all goes well. Still, they're small projects with very limited funding. Help them !

I use these tools everyday. Yes there are limitations, but for what MOST people need there are solutions. It just depends on what is important to you. Also, you can use the ellipse assistant.

This is actually an excellent comparison. I don't own a car, and I advocate for the car free lifestyle. I also don't recommend people using Adobe if possible.
