It was once possible to disable advertising about OneDrive, but Microsoft has reconfigured things so that's no longer possible without deep hacking (no user-level configuration options). There's an "Uninstall" option attached to the OneDrive client's listing in the Start menu, but if you choose the option, instead of uninstalling the OneDrive client, the system opens the Control Panel Programs & Features applet, where OneDrive is nowhere listed.
As time passes the advertising is becoming more aggressive and less controllable. On February 14th a commercial announcement related to Valentine's Day appeared, but I wasn't able to track it to its source. Just one example -- Microsoft is jealous of Google and they're becoming an imitation.
The deep issue here is that corporations have to decide how to most efficiently grow their companies. Do they pay attention to customers, or stockholders? At some point in the past (I think it was during the Reagan years) corporations turned their backs on customers and made stockholders the focus of their attention. And from a corporate perspective, it was a good choice, because customers are fickle and unpredictable, but stockholders only care about quarterly earnings reports -- no earnings and they walk.
Also, there's plenty of distros that look great out of the box.
Not to detract from the point you're making, which is quite valid.
