Disclaimer: I'm one of the co-founders of Monarch Money, a (paid) competitor to Mint founded by the original PM on Mint.com. I had written a HackerNews front-pager a couple years ago about why Revenue Model is More Important Than Culture [0], and my co-founder wrote some thoughts about why Mint ended up going this route.
Since this announcement, we've seen an unprecedented influx of "Mint refugees" moving over. I think a lot of Mint folks have felt like the product has been neglected for years, but it was free and they often had years of history in the product. This was kind of a forcing function for them.

GPT Neo was trained at similar expense, and they released the weights. Use that.
Router Nodes is what I would really like to have, I want a node that doesn't have internet connection, but in the local network with another node to get access to the internet through that node. Wasn't able to achieve it with plain Wireguard, my linux networking kungfu is weak.
EDIT: thanks, I'll try mentioned projects, Yggdrasil seems most interesting.
