Apple acquired CUPS (Common Unix Printing System) which is still used by a lot of Linux distros (like Ubuntu and Fedora).
CUPS was bought by Apple in 2007 and continues to have open source releases and continues to be used by major Linux distros.
For FoundationDB, there isn't really the same market. Most sites don't need a distributed database. People that run sites is already niche and people that run sites trafficked enough to require a distributed database is even more niche. I use HBase and Kafka a lot and there are definitely high-profile users of the software, but it's nowhere near the number of users of MySQL or PostgreSQL.
Maybe Apple will look at FoundationDB as something where open-source in no way hurts them and gets them free development. Google won't be replacing F1/Spanner with it so it's not much help to what a lot of people would consider Apple's largest competition. Plus, open-source could help make it better.
