I've worked for one of the big three you mentioned. Probably a different one, or at least a different group, since the culture seemed fine to me.

I can't think of single a time where old code or tools were a barrier to innovation. We updated when there was a real need, but otherwise left working code alone to focus on adding innovative engineering features. The code was so heterogenous that it was modular by default, so the pain of one library's tooling was limited to that one library.
