"We moved to GitHub because everyone's already there"

"We shut down the mailing lists because most of our users prefer to use GitLab in their web browser"

"We're rewriting in Rust because we don't really have any non-x86_64 users"

"We're leaving IRC because Discord is more user-friendly"

What all of these arguments have in common is that they exclude people, centralize infrastructure, and eschew free software for proprietary solutions, all in the name of some ill-defined measure of "progress".
