Well, I have the feeling
The feeling eh? Sure it's not a vibe? Feelings are the domain of soothsayers, charlatans, faith healers and other assorted crackpots.
Dave is not sufficiently motivated to do THE GOOD VIDEO
Given the interest shown in this particular supply, a follow up video would depend mainly on the availability of time and relevant and interesting content.
Asking him to remove the old video (or else?)
Or else? There you go having your feelings again. Dave has stated his position on such requests many times, something that has nothing to do with your old country
feelings or xenophobia
probably didn't help to motivate him to do THE GOOD VIDEO.
I am sure Dave will be overjoyed to think there are nutjobs out there that believe he'd put a desire for retribution before a need to call it as he sees it now. It may not be common practice amongst your secret handshake set but unless you've missed it completely, much of Dave's reputation is based upon his giving no bullshit calls based upon actual results.
I'll be interested to see what Korad has done to rectify problems and whether it constitutes a kludge to get it past testing or modification sufficient to give the thing adequate reliability and longevity.
Given that Dave will get an actual device and you're working from racial bias, tea leaves and other non specific jiggery pokery don't be offended if those of us with a clue wait for Dave's replies while ignoring your rants. Have a nice day!
