BBB typically facilitates comms in these cases. Indeed I have never gotten a BBB-inspired remedy from a quite large corporation. But large corps almost always respond to the BBB in my experience. It’s useful in the very least to force a corporation to talk. That talk can be used against them in court or presented to an attorney general.
I would rather have BBB compel a corp to talk than to lick Elon’s boots. Compared to Yelp and Twitter, BBB is the lesser of evils.
