Apple has a LOT of servers. They just don’t sell them (well, they do). But they care a lot about it; they hired the Netty team to work on fundamental server software stacks (which we know because it’s open source). If ARM servers mean more power efficient data centers then I can see them doing it just for their sustainability objectives which is a major priority.
If an Apple-developed server SOC was put into wide use internally for sustainability reasons, wouldn’t Apple be morally obligated to open source such a design?
It seems like a possible conflict if it had tech otherwise proprietary to the A series.
