They most definitely do. They have been lobotomized in some way to be ultra corporate friendly. I can only use their M365 Copilot at work and it's absolute dogshit at writing code more than maybe 100 lines. It can barely write correct PowerShell. Luckily, I really only need it for quick and dirty short PS scripts.
I agree. I asked it for some help refactoring a database and some of the SQL is quite broken. It also doesn't help that their streaming code is broken so LLM responses sometimes end up broken in the web browser (both Firefox and Edge so it is not a browser issue), so you need to refresh after a response to make sure the LLMs response was not an indication of a drunk LLM.
