It’s a large technology company and has significant funding to invest. But I see that Apple doesn’t own or co-own a submarine cable with another company, and I tried searching for it on Submarine Cable Map, but nothing came up.
Apple has its own servers, but also uses third-party servers for its services like iCloud. Meta has its own submarine cables, because Apple doesn’t own a submarine cable or doesn’t share ownership.
That’s like asking why General Motors doesn’t own its own interstate highway system.
It’s a totally different industry that just happens to be adjacent.
