It's common among Rust projects (the standard library also uses it).
Apache 2 has a patent grant so it's preferred by companies, but is not compatible with GPLv2, and MIT is compatible with GPLv2.

For completeness:
Apache 2 is compatible with GPL 3, which outside the kernel most of the world uses.

I'm... Not sure that is the case?
Some big projects still on (L)GPLv2, off the top of my head:
MySQL & MariaDB, QEMU, Busybox, Git, Wireshark, probably many many more.

Besides the legal reasons that others already explained, I use it because I want people to be able to freely copy-paste code between projects while keeping licensing uniform, and this is essentially the "standard" in the Rust community.
I see, thanks for commenting. I genuinely wanted to learn more about the background or context of that decision. Didn't know that it's a common thing to do in the Rust ecosystem! Nice to know, too.
I had always assumed that if the time came to choose a permissive OSS license, I'd just go with Apache-2.0 for the more complete legal ground that it provides (especially wrt. patents). Didn't even occur to me that it would as much as make sense to offer MIT too (like, why not also BSD now that we're at it?)
