In a sense, they aren't dangerous because you wouldn't dare to compete with them in some areas. Most notably, every freakin business in the world uses their Office Suite and there's no serious competitor. Think about that... software that everyone from college students to accountants to lawyers to investment bankers uses and there's only a single vendor.

In some of their other businesses, I'd argue that they are very scary. If you work at AWS they are a formidable competitor. If you are in the video game industry, they are a behemoth. But very few startups can really compete in this space, other than for the niches.
