The problem is "secure" is a vague term and thus easy to gamify.

eg is it secure because of fewer CVEs? You'd probably expect fewer CVEs because it is newer, so that doesn't mean it is more "secure" in any meaningful way but it's definitely an easy position to defend if someone were to challenge Microsoft's claim.

Look up the number of CVEs by OS and you'll find the results are... amusing.
