I’d rather see a robot blown up than a Ukranian defending his homeland. If you hate robots being used by Ukrainians then the only other option is people dying.
You’ll be glad to hear tens of thousands of people have already died in this war then, including innocent men, women and children. Many were tortured and/or raped first. So the human cost is absolutely massive already. No amount of robots can undo it. Hope to have eased your fears a bit.
A VPS on Hetzner with 2 shared vCPUs, 4GB ram and 40GB storage costs me less than €5 per month. I use it for services that are more “critical” compared to what runs on my home server.
