Considering they kinda botched the disclosure to Linux distros, I guess they wanted something most sensational to sell more licenses.
How recursive should their notifications be? Just the tip three distros? The top dozen? Every embedded Linux router company? How about every hosting provider?
They did what they're supposed to without being paid for it. The only other good source of funding for security research besides marketing budgets for security companies will NOT result in a disclosure timeline you'd be happier with. ;-)
