@ShannonB Ugh, I'm sorry that you're dealing with that right now!
Like @Coreyartus said, it's pretty bad if SCBWI went out of their way to release an article about it. Yes, they seem to make payments when people threaten to go public with the information, like @NessIllustration said. However, it seems that the cat is out of the bag now, so I'm not sure what their new strategy is.
I had a fun interaction with Cricket a couple months ago. They emailed me with the details on a project they wanted me to work on.
Their initial email:
"Our budget is $1,800. The deadline is April 4, 2023, for final art. Payments can be up to 6 to 9 months after the publication date (July/August '23) of the magazine."
My response:
"Thank you so much for reaching out. This does sound like a fun project and I would love to work with Cricket Media.
Before proceeding though, Iād like to ask about a couple articles recently published regarding payment delays at Cricket Media.

Has Cricket made any changes to address these delays?"
And this was their response a couple days later:
"I was told that the company will be releasing a statement concerning the payment delays soon."
(Note that is has been two months and no statement.)
Anyway, so I told them I'd be happy to work with them, but only if payment was received before the transfer of high-res files, and that was the end of the conversation. 
Lee's done some covers for them. I'm curious what his experience has been with them.
