Not quite…it was originally a southeast Asian sauce popular in China and Malaysia where it went by a name pronounced like “ke-tsap,” and it was made from tropical fruits like bananas and plums and fish sauces. Europeans tried to recreate it using tomatoes, and that’s how it became what is today.

That sounds like made up history trying to fill a hypothesis. In Britain, they give you vinegar with your chips. In New Zealand, if you ask for ketchup, they give you tomato sauce.
