Final answer:
No specific percentage is provided for the number of people who will never do business with a company again. The question would require explicit data from a survey targeting customer intentions after a negative experience with data use by a company.
Step-by-step explanation:
The question does not provide specific data regarding the percentage of people who say they will never do business with a company again after experiencing issues related to data collection or use. Based on the information given, there are statistics about people's concerns and feelings towards data collection by companies and the government, but there is no direct percentage related to individuals refraining from repeat business with a company.
To answer a question like this, one would require survey data explicitly asking customers about their intentions to continue doing business with a company after a negative experience. General concerns about data use are not the same as a declaration of ceased interaction with a company.
