"Awesome-HarmonyOS" is something like a fansite, nothing official. Gitee also isn't their "own" platform. Some of Huawei's projects have their code hosted by Huawei themselves (e.g. https://code.opensource.huaweicloud.com/HarmonyOS/OpenArkCom... ) but that platform is just horrible (especially on mobile), so it's probably a good thing they switched to Gitee instead.
