I wonder how much this will impact the economy in Russia? It seems they’re is not much point having a smart phone if all you are allowed to access is government controlled services.
Do the major phones get sold in Russia or are they all locally produced?
There are large areas of open source that don’t rely on volunteer labour because companies with a vested interest pay people to work on them. They tend to be the obvious large projects that are continuously developed and gain new features. The trouble with something like xz is it was mostly “done” (as in it did the thing it was intended to do) but still needed maintenance to address the minor niggles, bug reports and updates to tooling and dependencies.
The foundations could do a better job here of supporting the maintainers. After Heartbleed the Linux Foundation started the Core Infrastructure Initiative to help fund those under recognised projects. I would hope the people running that could be more proactive identifying those critical understaffed components.
Edit I think it’s now called the Open Source Security Foundation: https://openssf.org/
