Other than your opinion regarding what constitutes an "upgrade," which you are entitled to, almost everything else you wrote is incorrect.
The product (an open A1-15 boarding position) is literally named Upgraded Boarding. This is also the terminology Chase uses when referring to the free benefit included with the Priority card.
Upgraded Boarding offers one a lower number.
The free benefit is not available with the Premier card.
Business Select is something completely different -- a fare type, which can be purchased in advance or upgraded to from another fare type at the airport. The credit card benefit referred to here has nothing to do with Business Select.
