I noticed that while reading it as well. The call for funding ap few weeks ago did not sound nearly as dire. I wonder how things are going with that. I had wanted to donate to Matrix a number of months ago, but there was no easy, non-Patreon way to do that. I guess I assumed that with the new ask for donations and setting up DonorBox would have a pretty large response.
It's also strange how quickly this situation developed. I read every TWIM (at least I did before RSS broke recently) and follow the project and some developers on Mastodon, and don't recall hearing anything about financial woes. If anything, it seemed like at least New Vector was doing well financially. It isn't clear to me whether the financial issues are with Matrix directly, or New Vector. I don't think this is mentioned for the two developers who were laid off either.
Overall, the tone and urgency of the 2022 update struck me very off guard - not what I was expecting.
