To this day I’m the type to customise everything I own and I despise staring at generic looking programs all day. It’s even worse when it’s stuff like Discord that has a very opinionated style that won’t even respect the small amount of customisation my Linux theming gives me.
I feel like a huge reason the indie web died off was OSes and programs limiting user customisation which was a gateway drug for many. MySpace themes would get people learning html/css. Winamp skins got people learning photoshop/graphics. mIRC scripting taught people basic coding. OS customising had all of it. Now you just shut up and use it as they dictate.
