Pure speculation, but when they switched to "intel" they were effectively locked in, and they couldn't then have some intel and some AMD and some of their own x86 stuff. Now they're going to "Apple Silicon", it might be ARM this decade and who-knows-what next decade, but it will remain as reliable and fast and blah-blah as "Apple Silicon".
