[2022] Question about what specifically we're losing in Anno 2070 with the shutdown?

I knew this day would come eventually. I was ok with the DRM in 2011 because there was still a great experience behind it, but I often spoke/wrote that I live in fear that one day I wouldn't be able to play one of my favorite games of all time. However, I've been hearing mixed signals about what this all means?

So what will we lose specifically? The ability to transfer items VIA the Arc? Sucks but that's just a time saver. I can live with that.

The daily/leveling progression mechanic. That really sucks for anyone that didn't complete everything up until now. But if we've maxed all those things out will we notice any difference?

I heard that you won't be able to download DLC anymore. Is that true or just fear mongering because of some other titles? That would absolutely be apocalyptic if you couldn't play Deep Ocean or the cosmetic DLC anymore.

Any more clear information would be appreciated.
