Petty drama? On Twitter?! (haha, sorry.)
The biggest take-away for me is... people shouldn't feel instantly attacked if someone expresses preference toward one medium or another. Jake Parker is just one guy (who also does digital-- he's not a traditional purist) with his own preferences. If you like digital, and you want to do digital Inktober, then by all means do your thing.
I think digital and traditional inking each pose their own challenges, and it's worthwhile to become proficient in both. Personally, I find traditional forces me to be more conscious of my inking decisions, which translates into faster digital inking. I also like doing traditional Inktober because I do so much digital inking on my comic already, it's nice to change it up.
It reminds me of another Twitter explosion from a while back-- someone quoting a comic artist about how you shouldn't spend your career drawing other people's characters, and should make something for yourself. The quote implied that, if you spend your career working on Marvel or DC's IPs, you'll never claim ownership of anything, and to take time to make your own creations. But people twisted it into an attack on literally anyone who draws fan art, and of course all hell broke loose.
All in all, if you like what you do and it makes you happy, don't feel the need to viciously defend it every step of the way. Someone expressing a personal preference is not an attack on you as an artist. And even if someone was trying to insult a particular way of drawing... is their opinion really worth so much energy?
