Never heard of Bryan Lunduke before, but after a few minutes poking around, it's obvious that he wasn't de-platformed because of his thoughts on Linux or Rust¹².

Bryan Lunduke is a tech youtuber who has occasional commentary on extreme political ideas popping up in places like IBM, and his last video was critical of Rust-as-a-feature projects. I can't help but wonder if this is what actually got him banned, finally!

But in all seriousness, I don't really like his content that much, but it deserves voicing that YouTube have banned him. I don't think he's even that controversial, he's just upset the wrong FAANG people.
