Perhaps one of the more surprising changes in the 6.12-rc4 development kernel was the removal of several entries from the kernel's MAINTAINERS file. The patch performing the removal was sent (by Greg Kroah-Hartman) only to the patches@lists.linux.dev mailing list; the change was included in a char-misc drivers pull request with no particular mention.
The explanation for the removal is simply ""various compliance requirements"". Given that the developers involved all appear to be of Russian origin, it is not too hard to imagine what sort of compliance is involved here. There has, however, been no public posting of the policy that required the removal of these entries.
An early comment likely pins down the prevailing institutional pressures leading to this decision
What's the deal with an international project adhering to what is obviously a decision of the US government?
Hint: The Linux Foundation (which notably employs Greg KH and Torvalds, and provides a lot of the legal and other infrastructure for this "international project") is based in the US, and therefore has to follow US laws.
This is pretty fucked up. Like, we might see the kernel forked in the coming months/years.

Russia is a big country and if Russian devs are generally unhappy with this, they could likely maintain a Linux fork. Especially if devs from other big countries in geopolitical tension with NATO, namely China, also coalesce around this fork.
