The fact that many semiconductor different companies brought ARM based products to market, each with their own set of peripherals, hardware reference designs and SDKs targeting different verticals (in different ways). This huge variety of available off-the-shelf designs makes it possible to make cost-effective products with low investments and fast time-to-market. A CPU core alone is not enough, one needs the ecosystem and ARM understood that from very early on.
