I had a similar thought as whilst the technology might be similar in some ways the context, the history, the use cases and the driving principles are different. Anyone who has started a development job working on an established architecture and codebase should know that it takes months to begin to understand to a good level what's going on and why.

Opinions can be given but should not be taken as gospel over the opinions of the existing developers. But a lot of the time a new owner will take the opinions of their trusted sources (whose paycheck depends upon validating their boss' opinion) versus established experts. Good solutions come from discussion between these two opinions.
