This has bugged me for years but I've never voiced it. I've worked with about a dozen digital marketing agencies who all had SEO as their primary service, that was the focus of their website, and the only way they stayed in business. However, in all of those dozen cases - they had NO SEOs. In fact, they didn't even try to do SEO themselves. They just outsourced it to people like me - real SEOs. Why make the core of your business something you can't deliver on? I worked for a company that stopped doing work on their client's websites (who for some reason stayed with them) for over 3 months because their last SEO moved on. Is SEO really that misunderstood? Do people open web design companies without web designers and just outsource all the work? Do people open grocery stores without groceries and just buy them from other stores to resell?
