Maybe take a look at Wick Editor? https://www.wickeditor.com/#/ It's open source and development has stalled lately, but it has a stated goal of being a low-learning-curve flash replacement.
This is actually a great example. Wick editor is an awesome tool but it needs a lot of work to become the go-to tool for creators. You can see that the Patreon now pulls in 147 euro p/m, not enough to sustain someone working on it.
It's a (awesome) niche tool and to become mainstream (for designers) it needs more features, but there needs to be money to built those. A catch 22.
