Most of that is marketing, especially the bits about how the cloud enables all of this amazing functionality. The only thing the cloud is saving over local offline functionality is software development time. Your points about the control board are completely irrelevant since a local computer could run their software.
As an aside, I am getting pretty tired of GF staff and now some customers responding to criticism with “maybe this isn’t for you.” I completely get that especially @Dan is trying the cool and friendly approach, but I’d like more “I hear you, but it’s not on the roadmap at this time,” and less “Maybe this isn’t for you, let’s get a refund.”
I mean, I’m super excited, obviously; I ordered it a few minutes after the page went up. And I’ll make do. But criticism helps companies make better products, and there aren’t any technical reasons why offline functionality can’t be enabled, it’s just not something they’re choosing to focus on. I super hope that changes in the fullness of time, even if it’s something that would require me to have a linux box with a bunch of web stuff running on it.
This is generally how I feel about it. Despite living in a technologically advanced country, my internet is still not thaaat reliable. And while I don’t need four 9s of uptime, it’s going to be murderously frustrating if one of those times I want to do something on the 'forge overlaps an ISP issue.
