Take a look at "11. Disclaimer of warranties, limitations of liability, and indemnity" there is a section about commercial use.

I really don't know what you're talking about. There's nothing about commercial use in section 11 (nor does the language you quoted above appear anywhere in the Searching "business" and "commercial" makes it easy to verify this).

Section 11 point 4 "agree not to use our Services for any commercial or business purposes"

I understand they want to limit their liability - so feel free to call me naive...

I'm just old school enough to think that if I buy a tool - I'd have the right to use it and enjoy the results

Imagine buying a bread knife and be told what bread you are allowed to slice ?

Pizza needs an extended license.

No pineapple allowed

> Section 11 point 4

You must be looking at something other than the terms of service you linked, because section 11 has no point numbering (and just in case, the fourth paragraph of section 11 says nothing of the sort).

..while their support chatbot claims commercial use is fine. Oh well
