US general law.
Company [A] is in the digital services industry and has been in business for a decade. During their operations they receive many rave testimonials/reviews about their service.
"[A] has been exceptionally responsive... "[A] is great".. etc.
Company [B] then buys out Company [A] and assumes all operations.
However, the the name and/or branding does not change after the buyout. To customers, everything still looks like it is Company [A] and no visible transfer of services has occurred. Although the services are now entirely under the operations of Company [B].
Company [B] continues, for many years, to use testimonials/reviews related to the performance of the original Company [A]. Testimonials/reviews are in no way related to the performance of Company [B], under the guise of Company [A].
Company [A] technically no longer exists, rather it is Company [B] doing business as Company [A].
Can Company [B] continue to use testimonials/reviews originally referencing the performance of Company [A]?
Are the testimonials/review permitted merely because the visible "face" of the company hasn't changed? Even if the entire backend operations have?
