As someone who doesn’t work in tech, I mainly homelab as a way to learn about different technologies for fun. But I also like that I can invest in and control my own data, and don’t have to risk that my data will be inaccessible because a company goes under or changes their business model.
Few reasons. One, to help me advance in my career. Two, because I like the idea of open source. Three, tech business are kind of acting evil for money, so I’m going back to being self reliant and piracy.
