A quick web search suggests that you are probably paraphrasing a newsletter [1] that Joel Spolsky published in 2001. He was talking about software like Excel (of which he was the Product Manager) and Word. Maybe a tool that is more focused on a narrower task (like UI design) can be less "bloated"?

Agree. This quote is being used out of context here. Niche software can and does succeed especially when it’s only supporting a single dev. This isn’t trying to dethrone an adobe product, or doesn’t need to.
