Personally I just check the AP every morning and watch PBS News Hour over dinner if it's on. But I will poke around on Hacker News and NewsNow if I'm bored, which does have an option to check multiple sources like you mentioned (it's the stacked orange squares thing next to every headline). Both are 100% free.
And +1 for Ars Technica, I see them writing about right to repair a lot. Which I'm a huge supporter of.
Not a fan of speculation and we're likely to never see any official documentation, considering it's a military aircraft.
But I will say: If it is true, it's probably the dumbest thing you could do to an advanced fighter like this. Just imagine that you're in a conflict, then the enemy hacks your command and control systems and disables/hijacks all of your aircraft. Yeah, that's pretty dumb.
Even the Star Trek writers realized this sort of thing is a bad idea.
