Great idea. I’m sure Microsoft, Apple, Adobe, and almost every company that makes money with their software will be super happy to share their source code with me!

Edit: typo

When a basic dynamic library needs to be updated because, for instance, there is a big security issue, then all your statically linked binaries will have to be updated. Which means every one of those developer teams need to keep track of all the security fixes, release a new version of the binary and push it, and every user will have to download gigabytes and gigabytes of data.

While if you have dynamic libs you only have to download that one, and the fix will be pushed earlier and all the apps will benefit from it.
