Correct. Which is the point. The user complains that the problem is a software crisis when the software is fine on completely different hardware. That would suggest by elimination it's not a software problem, or is a software problem tied to particular hardware.
(incidentally they mostly use USB-C apple pencils and some clone ones when they lose them and the parents don't want to buy a genuine replacement one)
It is a software problem when a pen is used; you aren't using a pen so it doesn't impact you.
I don't understand why you thought it was constructive to point out the difference between a "software problem Vs. a software problem only when the pen is used." The article was very clear on that point already, it isn't adding to the conversation.
