That was also the case for CSIRO, Australia's largest government scientific organisation, when I worked there years ago. We had a lot of open source collaboration products but they were tightly managed and approved.

Legal were so backlogged that approval for anything other than a strategic project was impossible.

I was not allowed to submit work to unapproved projects, other than my personal stuff I'd listed as my own IP on being hired.

It's usually about IP protection ahead of brand protection.
