Business Wire isn’t a news wire service, though. Examples of those would be the Associated Press and Reuters. It’s a wire service for the distribution of corporate press releases, which by definition are going to be biased.
That’s not to say there isn’t a place in the news world for services like Business Wire - corporate press releases can be valuable sources of information. Just that any reporter who would take something off Business Wire and run it verbatim as a news item is not very good at their job.
