Before anyone publicly burning down a classic High-Tech company, realize bad results can come from several causes. Be it just a not-viable business in its core, be it unexpected extreme costs to get products out, beyond the technical capabilities of the business, be it product-repairs due to breakdowns before expected EOL or product defect damage payments.
When the core business is not viable, there is little else possible than to close down / sell-out the knowledge.
The other 3 items do look more like what Boeing happened to experience with the 737-MAX: Customers over-asking the companies' capabilities. My bet is the latter happened to RR, customer(s) requesting more, than where (top-) management dares to say "no" to, under shareholders pressure for more profit & shares value. Happens across all industries, more and more, especially when competition is perceived fierce.
