Use a computer with a mouse. Steve knew what usage scenarios are valid for a tablet and what for a desktop computer.
So you would rather technology just stop, so we can limit certain interactions to our computer (that can very practically be applied to a tablet or even a smartphone) because you don't think other people should use a stylus to mark up PDFs on their iPad?? Because eight years ago Steve Jobs said something that is now taken grossly out of context?
When the iPad 2 came out, I had a friend who bought one and found a good PDF markup app which he used, with a stylus, to take notes on the hotels he had to review for his job. Yes, the iPad 2. Back when Steve Jobs was alive. Interestingly enough, Steve Jobs never contacted him and asked him to stop using his iPad for inappropriate usage scenarios, nor did he tell my friend that he should put his iPad away, take his notes on a yellow legal pad, and do any markups at home on his computer instead of doing things he'd rather be doing when he wasn't on the job.
Tell me, please, how drawing, writing and marking up documents are not appropriate for a tablet computer with a touch screen on it? Also, remember "Think different?" Explain how "Use a computer with a mouse. Steve knew what usage scenarios are valid for a tablet and what for a desktop computer." fits in with that ideology.
I don't know if people like you understand this, but
Steve Jobs is dead. We can't hear his thoughts about the current tech industry (READ: eight years after Steve Jobs said "yech!!" on stage towards the stylus) because he is no longer around to give them.
Let's also keep in mind that the topic here is a rumor that Apple is releasing a DIFFERENT iPad that might include a stylus that DOES NOT HAVE TO BE USED AT ALL. Apple is not canceling all other iPads in lieu of a huge one with a stylus. Apple is also not paratrooping into your household to take your iPad away and replace it with one that requires a stylus. If there is an iPad Pro, there will still be an iPad Air and (I hope) an iPad Mini. There will also be the iPhone 6 Plus which, in spite of being a much larger phone, does not incorporate a stylus.
So I have great news: Apple will most likely never hold a gun to your head and require you to buy something you don't want to buy.
Also, as somebody else on here already pointed out, Apple started taking out patents for a stylus in 2010. Fun fact about 2010: Steve Jobs was alive and the CEO of Apple that year.
