There are lots of types of people with different opinions and backgrounds on Lemmy. However, most of us in the core user base came to Lemmy either because we were pushed out of other online spaces, or left out of protest. This means that Lemmy is tends to have a bit of a bias against big tech, authoritarian governments and corporations, etc. Lemmy is also open source, so there is also a strong do-it-yourself sentiment here. Lemmy also attracts folks who remember Web 1.0 when information was decentralized, with no top-down control. There are still users and whole communities that disagree with the majority of Lemmy users, but you have to look for them because they are in the minority and are thus not raised by the voting-based systems that Lemmy uses.
