There's a simpler reason to link nearly everything statically. Besides libc, almost everything is built from source, and not just from source, but from source as it exists at the current revision. So compatible re-use of prebuilt *.so's would be a nightmare and you have two realistic choices:

1. Build them all at current revision and package them as a subtree. This is utterly pointless since due to containerization there will be no library sharing anyway. The only real reason you might want to do this is to save time on static linking.

2. Link statically and ship a single (often enormous) binary with just the stuff you need, saving a bit of disk space, and a bit of time at runtime. Fewer moving parts, what's not to like?
