I think most people just assume it's magic, and are too awestruck by the hype to think critically.
Financially this feels similar to Uber's business plan in the 2010s; undercut the market with unsound pricing propped up by venture capital (PE was literally subsidising taxi fares; they admitted this and their intention to readjust, but no one seemed to care) then stop manipulating the market and allow fares to even out at (gasp) what it cost to get a cab before Uber.
The difference here is that the LLM market is human productivity; enormous subsidies are afforded to Anthropic, OpenAI etc. in the form of VC or compute credit, but eventually those debts will be called in, the free-to-use aspect will vanish because it's simply not profitable, and we'll be left with several premium products that only a few people will actually pay for, and even then that may not be enough to cover their costs. That's when the bubble will burst.
Anyone calling anything an anti-pattern without evidence always sounds to me like 'I don't like how you do this, but I need to find a more cerebral way of describing that so I don't sound like a child.'
Like a product I wouldn't touch with a bargepole.
