Ask HN: Why is it OK for Cursor and Windsurf not to credit their model

Windsurf's SWE-1.5 is really good, and I've heard good things about Cursor's model too.

However there's this nagging feeling I just can't shake: using the base models without credit is not OK.

I know they've done some post-training and a lot of work optimizing the inference, but to use something as substantial as an LLM and not even credit them feels super wrong.

I guess my question is how is this OK, regardless of what the licenses allow.
