Steam Deck easily. Everything you said you’re worried about Valve possibly doing in the future goes double for Microsoft.
Steam Deck is a great platform for playing any games on, pirated included. I have my whole GBA ROM collection on my Deck and play them through RetroArch, works perfectly.
Favorite heavyweight Type 1 hypervisor: XCP-ng. It’s open source, runs on a ton of enterprise and consumer-grade hardware, has always been rock stable for me, even when forgetting to update it for like 6 months, still ran everything like a champ.
I need to try ProxMox, has some cool features. XCP-ng is pretty intuitive though, UI makes sense and is cleaner than Proxmox. The integration in Proxmox with the Incus project is pretty cool though, especially being able to run VMs and containers and manage them together. I’ve been thinking of trying that and seeing how it goes.
For containers, I just install Debian and run Docker on there. Stable, simple, nothing fancy. If I need something more up to date, I typically use Ubuntu Server.
