Na, it's perfectly reasonable to expect people who claim to care and genuinely want to know, to make a minimal effort.
"I tried looking it up but couldn't find an answer, do you mind helping me out"? Sure, no issue here, wouldn't have even mentioned it. But to drop in to a conversation without knowing anything about the topic, and expect disabled (or otherwise marginalised) people who are personally impacted (and therefore constantly having to have the same emotionally laborious conversations over and over and over) to do the work for you before you've even tried? That's going to get (seriously fucking gently) called out every time.
I have the same poor quality search engines at my disposal, and have to sift through similar results.
There is also an easy way to recognise actual advocacy sources vs industry publications - is a disabled person writing from their personal experience? Advocacy. Is the article written by someone who isn't personally impacted? Irrelevant. Simple.
E: The fact that I went ahead and did the work for them anyway despite all of that (with, again, the gentlest of reminders that they could be doing it themselves), and people still find a way to complain about how supposedly unaccommodating I'm being is fucking wild..
With regard to the astroturfing, are you saying that the sources people might find are AI? Sure, that's definitely a thing that is happening, but I'm not sure what I'm meant to do about that? I'm no better than the next person at recognising AI and would need to read through and make a call just like anyone else (and then we open a whole other can of worms of rating the writing and or expression levels, and potential use of assistive tools of, especially in this case, fellow disabled people, which can become really problematic, really fast).
Like I say, I'm perfectly happy to help, especially those who have shown even a bit of initiative, but there's only so much I can do, and really, the burden shouldn't be falling on us to not only educate those with more privilege, but also become expert at deciphering AI use (and within that, legitimate vs intentionally manipulative).
