I have my own war stories from working at Qualcomm. Gather together, children.
Ahem. One upon a time I was the tech lead for one of the many software components in Qualcomm's GPU software stack. At one point there was customer interest in caching certain blobs of data that were relatively costly to compute, in order to reduce the startup times of a wide range of apps.
Since the caching needed to happen across different processes over time, we needed some sort of persistent storage with some metadata to track stuff like usage stats, limit storage requirements, etc. Simple stuff, right? I decided that we didn't need to reinvent the wheel, and thus suggested to the team's most recent hire to use SQLite.
Oh, Dear Lord. That was a mistake. SQLite worked great, no, no. That wasn't the issue. The problem was obtaining approval from Legal to use SQLite in our little project.
"Does SQLite have one of those viral licenses that require you to open-source your own code?" -- you may ask. No, it doesn't. It is the most lax OSS license that you could ask for. Super friendly to commercial closed-source projects.
No, the obstacle was that Legal wanted to audit SQLite line by line, down to the books and research that was mentioned in the comments, searching for anything from copyright infringement within SQLite itself, to patents that may be associated with any of its features. IIRC, it was going to take months and would require approval by my management chain. And any time we wanted to upgrade the version of SQLite we shipped with would require another extensive review.
The feature was canned unceremoniously. Fin.
