I've worked in two small companies and people get attribution for what they did. It is so much simpler to know who is involved, and nicer, too. You can reach the right people when needed.

The time someone takes credit for my work and refuses to fix this, I run. I can, there are so many nice places one can work at, especially with the raise of remote work which I happen to like.

I would not expect my bosses to take my credit. And I do recognize their involvement too. Actually, we edit a public open source project and publish extensions for it, and individual contributors are listed as authors, instead of just the company name.
