How about a thread title change to "Entitled gamers struggle with reading comprehension, hilarity ensues"?
Where else were they gonna blast it? To their developer faced official...oh wait they don't have one?
Sony doesn't have a list of every development studio to send out in a mailing list, particularly with independent development studios popping up so regularly. They already lost that audience at GDC when it got cancelled, but everything was in place for this talk. This was their easiest, most cost effective way to capture that audience.
By June, literally no one will care how this was delivered, what channel it was released through, or how upset they were that they watched an entire video specifically communicated as a tech deep dive by a computer engineer. Come June / July, Sony will be in full PS5 media blitz mode, with regularly scheduled State of Play reveals going out and leading up to launch...and literally no one will give a shit about this one specific moment in time.
