Anything hyped on Hacker News. Tech bros are only about their big payday. Very little of their shit improves the world and they disrupt industries and social structures without creating worthwhile replacements. They receive too much attention and have way too much access to capital which could be used more productively elsewhere. They are ruining my enjoyment of technology. I am very wary of services infringing my privacy, stealing my intellectual works, leaving me open to hackers, marketers and predatory business models, putting people out of work, promoting unfair employment practices, disconnecting people from their friends, family and community, promoting social division etc.
The biggest similarity with Windows is that it isn’t a community run project. In my opinion they tried very hard to represent themselves as an open source community in the early days and downplay Canonical’s role. There is nothing wrong with Ubuntu as a first introduction to Linux but if people are looking for a project to join and make contributions there are many better options.
