Project Zero's disclosure policy as described in the article appears to leave little room, if any, for the bias you appear to be implying:
> In keeping with long-standing policy, Google’s vulnerability research group gave Microsoft a seven-day deadline to fix the security flaw because it’s under active exploit. Normally, Project Zero discloses vulnerabilities after 90 days or when a patch becomes available, whichever comes first.
In addition, the two bugs appear to be unrelated other than being used as part of the same attack chain. The Chrome/FreeType vulnerabilities were reported on 2020-10-19 [0, 1], while the Windows vulnerability was reported on 2020-10-22 [2]. The Chrome team released a fix for their bug the day after the it was reported [3], while Microsoft is either still working on fixing the bug or is waiting for Patch Tuesday.
