Benjamin Mako Hill's "Free software needs free tools" is a classic piece advocating for the hardline "no proprietary dependencies" stance: https://mako.cc/writing/hill-free_tools.html
In open source communities, the topic now comes up most frequently in relation to "Why can't you just use GitHub, that would be so much more convenient for me..." complaints directed at open source project maintainers by folks that have been co-opted into GitHub's marketing arm by their well-crafted, venture-capital backed, freemium business model. (Which actually has a nice positive externality, in that doing more of your work in the open reduces how much you need to pay GitHub for repo hosting)
