Thanks to Yuki for informing me about this.
Last week, uBlock Origin maintainer RraaLL added filters to uBo's Badware List which display a message on ublockorigin[.]com stating
This is not the official uBlock Origin site.

This comes after the site began promoting a project named uBlockDNS, which is unaffiliated with uBlock Origin. Multiple reports on Reddit show uBlock Origin users installing uBlockDNS under the mistaken impression it is affiliated with uBo.
According to a comment on Reddit by a member of the uBlock Origin team, the status of ublockorigin[.]com was being discussed in internal discussions. It is unclear if this commit is the result of those discussions.
