I fully agree most big tech companies are pretty bloated. But FWIW a lot of my time at SaaS companies, especially in the B2B space, was spend working on features for larger customers that most others would never use or even see. Like, yeah, product X isn't that complex, but $BigCorp wants to use it in their private cloud, or needs it to be single tenant, or needs these audits done, or want their $Gov client to use it. Now you have a ton of work for zero visible changes.
