I think most people in theory are against big corporations, but when it comes down to it they just go ‘it is what it is’ and just accept the big corps without any attempts to break off that path.
My wife is like that and I think it has more to do with not being very tech savvy/or willingness to try something different.
Not a proxmox pro by any means, but it can do both VMs and containers. I have a few VMs for various Linux distros to play around with. I also have one dedicated VM for all my security related tools.
Stuff like PI hole, jellyfin, logstash, etc. dont really have any need for a full OS, so a container works perfectly. Plus having a full OS with several things running on it makes it more difficult if you just need to restart one service
I started doing everything in VMs but over time realized some things were better to maintain as containers
