The easiest way to see 'privilege in #FOSS' with your own eyes, is probably to observe how the people arguing for sketchy sponsors, legalistic moderation procedures, "neutrality" in moderation and government involvement, are virtually always white dudes - and those opposing them are everyone else (and, often, a small subset of white dudes).
Like, you don't actually need to believe me on this. Just keep an eye on who is saying what for a couple months. You'll see the patterns.
(Obviously this only works with people who disclose that information in their profile. There are usually enough of them.)
