It seems that as of the latest update, not all chrome plugins can be disabled. (or possibly

Google's now-mandatory Widevine had a critical flaw for six years, which was only reported because a researcher from Israel, the only industrialized nation that doesn't have a law protecting DRM, published his findings.
Though this departs into another nasty can of worms itself, where security researchers are being prosecuted (rather than just
persecuted) for publishing security vulnerabilities even when using "responsible disclosure" policies. So, can't talk about it, can't turn it off. Just "bend over and say 'aaaah'"
