Lawyers entire job is to make convincing arguments for any position you want, by artfully speaking only true facts, no matter what the position is and no matter what the facts are.
Of course a lawyer can and will say that you "can't" let any gpl software pollute the companys product "because the gpl prevents it", instead of saying that the company doesn't want to pay the license fee for the software.
The facts of the gpls terms may be true, and the lawyer may present them for their argument, but that still doesn't make the overall assertion true.
They can use gpl software all they want. They just don't want to. And good for them. That is better than simply stealing it which many do.
It's also merely an assertion that "most" open source software uses apache/mit/bsd wthout some numbers and citation. But that sentence could be parsed more than one way. They might have only been saying that most of the projects that use apache/mit do so for commercial compatibility reasons.
