I disagree. These devices can easily burn down people's homes if given bad G-code. Then they would be sued into the dirt for a security whole a mile wide. Looking at the changes this is about liability.
This is basically the equivalent to having passwords on a MySQL database or redis server.
Why on earth would they add a subscription? That makes absolutely no sense business wise. No one would buy their printers, and they don't have a captured market to strong arm anyone.
I personally do not want my printer connected to any vendor's server in any way...IMHO, there is no reason for it.
