It means "I have a useless education in a subject that produces nothing of worth."
Also "I know this whore actually publicly advertised her prostitution services 'discreetly' from the same social media as she did PR work for a children's company, but watch me bury that fact in incomprehensible SJW bafflegab."
Let's look at this:
"They fail to recognize that just because someone makes a product that is publicly accessible — or worse, because someone is tangentially and distantly involved in the making of a product that is publicly accessible — does not mean that they themselves should be, in their entirety, accessible to the public."
Okay, let's start with the 'they' beginning. Some vague group.
Then there is literally nothing with any meaning for the entire middle of this word sandwich.
Finally "does not mean that they themselves should be, in their entirety, accessible to the public."
This is why, if you don't want to be "accessible to the public" that you don't advertise that every orifice in your body from your mouth to your asshole is, in fact, accessible to the public, on a public website.
