Shadowing Experience

My first shadowing experience for Jour 4450 left me with some concerns. I think I noticed a conflict of interest with the company and whom they choose to work with.

The company, "Company A", completes thousands of tests for various businesses, mainly in the automotive industry by testing fuels and engines. An interesting aspect of "Company A" was that it choose not to promote its name, allowing it to work with whomever it wants.

"Company A" has ethanol and diesel fuel producers as clients. One of Company A's ethanol clients put "Company A's" name on its product and its diesel clients were fairly upset because ethanol and diesel fuel have to compete with each other in the market.

Is this a good, ethical reason for choosing not to promote a company name?

Any feedback is much appreciated.
