Letting a professional editor shorten your article

Dear community,

some common professional editing services (Taylor and Francis and others) offer, to not only proofread your article, but also to shorten it for up to 20% of its length. As my articles always are longer than the journals´ guidelines demand, this service would be attractive for me. Besides the question, if the editor can actually know where to shorten a philosophical text: Would you say that utilizing this service counts as cheating/ bad practice? I do not want to cheat or conduct bad practice.

Thank you and best regards
