The biggest issue I have with this 1% fallacy (which is a huge pet peeve of mine) is that it shows completely the wrong mindset needed for success in my opinion. To me it is saying we don't have confidence in our ability so we're going to target such a large market that if we even have a small amount of success we'll still make a lot of money. Your aim should always be 100% market share. If you don't think that is is possible to create a product that would be appealing enough that everyone in that market should want to use it then narrow that market into a smaller subset and aim to get 100% of that. You should never be ok with only 1% of target users using your product.
