I think this is only true to an extent. In my own career, I've worked for and hired people who were honest about their roles, taking a reasonable amount of credit where appropriate while also owning the things that didn't go so well.

In tech, there's really no downside to this because the industry is pretty damn forgiving. Failure is expected, and a lot of super successful people had multiple failures under their belt before they succeeded.

It's really, really cringey to have a LinkedIn bio where you basically position yourself as the owner of a product and then elsewhere make it sound like you not only had nothing to do with said product's failure but in fact knew how to make it successful but couldn't because everyone else was flawed in some way.
