This wasn't possible before flat design, design was a hard technical skill requiring use of light sources, noise for texture, and carefully constructed gradients and shadows. Flat design is mainly just text on large swaths of color, which makes it much easier for someone to just jump in and edit a Figma file (e.g., this was not possible with the much more complicated Photoshop setups folks were using before to create designs like this https://www.anandtech.com/Show/Index/4485?cPage=3&all=False&...)
(Note on a long-enough timeline, it's not clear how this is all going to end up. E.g., if something like Apple's Liquid Design catches up that'll move the needle back in the other direction towards more complicated software to create complex lighting and refraction effects. Note that the problem with Figma isn't that it can't add these features, it's that adding them will make the software more complicated, which will reduce the value-add of it being a web app, because the more complicated the software is, the more difficult it is to use collaboratively. Simplicity is really what facilitates collaborative editing.)
