The "corporations are people" thing is exaggerated in a lot of understandings, and I doubt corporations are deemed capable of "personal communications". Still, personal communications might be found to cover the communication among persons at the companies. But Slack does support a lot more than just people chatting with people, like bot and app/SaaS integrations. Those clearly aren't personal communications and frequently accomplish more than just exchanging information. Good catch that the license does have provisions for fee-based services as well. However, the person I was replying to quoted the one for no-cost services, so that's what I focused on in my reply.
