Yeah, "make it my religion" is a bit extreme - these are, as you say, software tools. Nonetheless, I do think it is bad that a lot of digital infrastructure for free/open source software, such as crates.io, is dependent on centralized services run by large corporations such as Microsoft-owned Github. It is important for free software hackers to develop free alternatives to this infrastructure that don't rely on e.g. having to have an account on a service wholly owned and run by Microsoft. Radicle is a really neat software project precisely because it is an attempt at building something that does the same job as Github, but without having to use proprietary software hosted by Microsoft.
