External Service Lookup Now Enforced During Sign Up - Why?

Integrated signup pages (i.e IRS/CRA lookup pages) have the company information fields set to read-only so that registrants can't change the information from what is listed and extracted from the external sources.

Prior to this update, registrants using IRS and CRA lookup pages could modify data (address, city, state, etc.) returned from the lookup service. This update removes this ability, and ensures that the information submitted during the registration process is the same to the data that exists within the original lookup service.
