Telemetry in Alibaba MNN: no opt-out, obfuscated server url

The info is in the __init__() function:

  self._url = base64.urlsafe_b64decode(b'aHR0cHM6Ly8xMDMyMjc3OTQ5NDA5MTkzLmNuLWhhbmd6aG91LmZjLmFsaXl1bmNzLmNvbS8yMDE2LTA4LTE1L3Byb3h5L21ubi1zZXJ2aWNlL3dvcmtzdGF0aW9uLXN0cy8=').decode()
  self._endpoint = base64.urlsafe_b64decode(b'aHR0cHM6Ly9jbi1oYW5nemhvdS5sb2cuYWxpeXVuY3MuY29t').decode()
  self._log_project = base64.urlsafe_b64decode(b'bW5uLW1vbml0b3I=').decode()
  self._log_store = base64.urlsafe_b64decode(b'bW5uLXRvb2xz').decode()

The strings decode to:

  self._url = "https://1032277949409193.cn-hangzhou.fc.aliyuncs.com/2016-08-15/proxy/mnn-service/workstation-sts/"
  self._endpoint = "https://cn-hangzhou.log.aliyuncs.com"
  self._log_project = "mnn-monitor"
  self._log_store = "mnn-tools"

I wonder why they obscured the URLs in that way. It seems so stupid, given how trivial it is to decode base64.

What does MNN stand for?
