Not true. Models don't make owners money sitting there doing nothing - they only get paid when people find value in what AI is producing for them. The business model of AI companies is actually almost uniquely honest compared to rest of software industry: they rent you a tool that produces value for you. No enshittification, no dark patterns, no taking your data hostage, no turning into a service what should've been a product. Just straightforward exchange of money for value.
So no, it doesn't such for everyone except them. It only sucks for existing businesses that find themselves in competition with LLMs. Which, true, is most of software industry, but it's still just something that happens when major technological breakthrough is achieved. Electricity and Internet and internal combustion engines did the same thing to many past industries, too.
