Summary: A quick push to fix something I noticed while studying how IGListKit works. This simply replaces "Facebook, Inc" with "Meta Platforms, Inc" in all of the source files where the company copyright notice is posted. This should help bring our external facing projects more in line with our new corporate branding. There's still a lot more references to "Facebook" as a company in the library (especially around linking to other Meta sponsored open source libraries), but this might need additional scrutiny and review on a case-by-case basis, so let's handle those ones separately.
