I don't really buy that excuse any more. This is a business that wants to have heavy, fast-moving objects automatically navigating complex and unpredictable transport networks using its software. For that matter, this is a business whose golden goose is prioritising content people most want to see on the scale of the entire WWW, which has no shortage of junk sites that exist primarily to game the system. I'm reasonably sure that same business can be smarter about spam recognition than defaulting to assuming new mail from a source it hasn't seen before is bad, which seems close to the practical output of its existing system. But as with so many of the current dominant tech businesses, until someone poses a credible threat to its existing business model and revenue streams, it has no reason to invest in fixing problems even if it could obviously do better.
