ByteDance shared the TikTok content recommender, which I'd argue is somewhat close to an ad recommender :)

You mean the paper, not the source code?

Plus it helps them recruit engineers who are already familiar with their tech stack.

Actually... (2019) https://ai.meta.com/blog/dlrm-an-advanced-open-source-deep-l...
Source code:
https://github.com/facebookresearch/dlrm
Paper:
https://arxiv.org/abs/1906.00091
Updated 2023 blog post, but solely for content recommendation, but ads recommendation is ~90% the same:
https://engineering.fb.com/2023/08/09/ml-applications/scalin...
It's a little out of date, but the internal one is built with the same concepts, just more advanced modeling techniques and data.
Meta is one of the biggest contributors to FOSS in the world. (React, PyTorch, Llama, …). They stand to gain what every big company does, a community contributing to their infra.
You’ll note that nobody is open sourcing their ad recommender, that is the one you should be skeptical about if you ever see. You don’t share your secret sauce.
