It's just a problem with the industry that's like "let's just get something out there and achieve product market first..will worry about infra and security later" that later is just pushed into a backlog and forgotten.
Some developers seem to be pushing that ops shouldn't exist any longer or should be outsourced to google (who don't hire ops) or amazon (who do).
Managers see this trend and think that hiring only developers is a good way to save costs and do things the "new way".
Traditional ops roles are indeed not as required but security/process/reliability focused people should not be the same people who write new features. They're in contradiction of each other often.
If you're a developer who thinks ops shouldn't exist any longer consider this:
I can write software and design websites as a sysadmin, does that mean I don't need you now, or that I know everything you do?
I argue that it doesn't. A focus on automation is one thing but defenestrating the notion of operations/SRE is going to net you a bad time.
