1) among non-tech decision makers, it's hard to keep out excess features and excess content, because that means most people don't get their pet project onto the website. The compromise is "everything goes in", which gives everybody a successful project that they can point to (successful in the sense that it got on the website)
2) among tech decision-makers, i.e. alpha developers and young hotshots, the urge to use what FAANG uses was very strong, because that's how you get the trendy tech on your resume. Basically the same at (1), above, but for developers.
Exacerbating this is that each additional thing is only a small part of the problem: "No single raindrop believes it is responsible for the flood"
