Software, 1,000%. I love linux and daily drive it. But when I have videos to edit, photos to rework, or collateral to design I have a windows laptop with professional grade tools to do the job.
I’m sorry, gimp is hot garbage. There isn’t a pro-grade, open source video editing tool or anything close. Inkscape is useable in a pinch. Scribus is useless.
Not everyone is a multimedia creative professional, but most software on linux never quite have the features you need, are no longer maintained, or will be useful in ten years.
That said, I’d still rather break out the laptop when doing client work than daily drive MacOS or Windows 11. Either way the barrier for most users is that linux almost works.
There aren’t many ways to organize raising the money required to build a better youtube or reddit. You could kickstart it, but you’d better hope whoever does the dev doesn’t sell. Another option would be a large open source ngo funding the development, but you’re still talking long timelines to completion.
There definitely is room for a more pro-social social media platform that isn’t a clone of something else. Paying for it is another matter.
