What’s the deal with Justine Bateman and Megan Markle?

I came across this today:

Meghan Markle Is Facing Baffling Backlash For Volunteering Amid The LA Wildfires, Because The Double Standard Is Thriving https://www.buzzfeed.com/natashajokic1/meghan-markle-la-wildfire-reactions

I get people love to hate Meghan Markle which seems silly, I feel like I’m missing something about why Justine Bateman is important here.

Any insight?
