And the technical arguments in favor of code signing are weak. They started off claiming a major benefit -- globally disable malicious code. Except that AV can do that too. The argument in favor of having code signing on top of that then becomes weaker -- AV can stop identified malicious code but it can't stop other malicious code from the same malware author. Except that code signing can't do that either since the malware author can sign other versions with different keys. So then the argument becomes, well, at least it rate limits how many different versions there are. Except that is only meaningful to the extent that getting a new key is arduous and not a lot of people have them, otherwise the attacker can get arbitrarily many more by either just applying for more under false identities or by compromising a moderate number of machines to capture more keys from the large number of people who have them. Moreover, using domain validation would already capture the case where you want to get the incremental benefit achievable from a minimal imposition on the developer.

Meanwhile the process of obtaining a code signing key has to be sufficiently easy and non-exclusive that even individual developers can reasonably do it, so making it purposely more arduous than that is a directly conflicting requirement.

The explanation is long because the details are relevant, not because anything "obviously technically inaccurate" is there.
