Why is there a lack of free and open-source editing software that's actually good, fully-fledged and usable?
Look at proprietary commercial ones that are industry standards like Adobe (Photoshop, After Effects, Illustrator, Flash, Premiere), Microsoft Office (PowerPoint, Word, Excel), digital audio workstations (FL Studio, Ableton, Renoise, Reason), 3D modeling (AutoCAD, ZBrush, Maya, Cinema 4D), game engines (Unity, Unreal Engine, GameMaker), Paint Tool SAI, Sony Vegas, etc.
Do you really want to be a slave to subscription models and subjected to piracy extortion scams?
It will get worse every year from now on if no one's gonna do anything about it, encouraging us to consume soulless corporate slop instead of producing our own creative works, as well as learning something new from the source code, to add our own tools and features, instead of having to beg them as a request to add it. No wonder why everything's being oversimplified to the point where newer generations become computer-illiterates when technical details are shoved under the rug and we just pretend it works like magic (look at AI for example and how it's being used to make profit, as well as Apple products).

We can only assume you work for a non-profit organization.
You might be more comfortable living in a communalist location.
Gimp is a suitable substitute for Photoshop in my experience. And you really don't need Microsoft office anymore because Google built a fully-functional online clone that you can use for free. And if you don't like Google's policies you can opt for Zoho. I'll admit Audacity feels a bit clunky, but I was still able to do mixing with it and got positive feedback on the work I did.
