It's not sabotaging it by using a worse model but by changing your prompt in your background, which means it silently destroys your code. Also I asked questions about whether it's safe for me for example to work on just compilers or just inference kernel optimizations and it refused to answer me. If I can't even ask what I can do safely without my code being destroyed, I just can't trust it not to sabotage my work ever.
