I switched to Bitwarden after the LastPass stuff a couple years ago, and I just got around to installing Vaultwarden on my TrueNAS system at home. Using a single Cloudflare Tunnel to handle secure external connections for that and other services like Emby easily. Took a little bit to setup following some guides, but has been working flawlessly for me and some friends. You can use the regular Bitwarden apps and extensions since they natively support self hosting.
This is one of those situations where adhering to the treaty doesn’t actually do anything positive, it just handicaps Ukraine’s options.
A primary reason for the treaty is that landmines are indiscriminant and they last well beyond the length of the war they’re placed for. So civilians are at risk decades after a war ends. The intent is to prevent ANY mines from being placed, by having everyone agree not to place them ahead of time.
However, Russia is going to place mines anyway no matter what. So there are going to be landmines in the area because of them regardless even if Ukraine doesn’t place their own, so the danger will already be there, except Ukraine will have one less tool to fight with.
