HN commenters sometimes ask why bother with DNS-based ad blocking when one can just install a browser extension.
This is why.
There seems to be one assumption that all online advertisers and telemetry implementers make. They assume the user is not in full control of name resolution. ("Full control" as used here means relying on whitelists not third party blocklists.)
In this case, they assume motd.ubuntu.com will be resolved without any user input. "Without any user input" here means the user never looked at the domain "motd.ubuntu.com" and made a decision whether it was needed or not.
