I hate to break this to you (large financial here, large COBOL installed base) but we're not just sitting around watching it run. We have hundreds of COBOL programmers, and they actually touch the code. I bet every day even. Crazy, right?
Just because some low-knowledge 'journalist' in a low-content rag decorates their ad-delivery with a low-effort 'you should have outrage about something' articles doesn't mean you should buy into it.
"If it ain't broke - don't fix it." does not mean "don't maintain the things you own - just let them run until they break - then fix them."
