But the good news is that Microsoft appears to be backing away from GDI, and its “Xandr” ad system will no longer be using the GDI blacklist to cut off sites.

The Microsoft-owned Xandr, a major advertising company, previously abided by a secret blacklist of conservative news compiled by the Global Disinformation Index, a British organization with two affiliated U.S. nonprofit groups. Now, as Microsoft appears to be taking steps to distance itself from GDI , the company has, for the time being, deleted flags such as “false/misleading” and “reprehensible/offensive” for right-leaning websites, data show.

“I just checked in Xandr’s platform again and can confirm that all rejection flags have been removed from domains,” a senior executive in the ad industry, who was granted anonymity to speak candidly, told the Washington Examiner.

Xandr had labeled 39 conservative domains as, overwhelmingly, “false/misleading,” the Washington Examiner reported on Friday. Townhall, a website under a Christian publisher called Salem Media Group, was flagged as “reprehensible/offensive.”
