I think the "killing" of the control panel is a good move and should happen. The settings app is what they were wanting to replace the control panel. One the major gripes I have with MSFT is the half-assed implementation. We've been dealing with overlapping tasks/services between the control panel and settings app far too long.
As for the "harassment" Since I'm a gamepass and office 365 subscriber, I don't see that, I guess I'm one of those consumers that just fall into what MSFT is offering. You can uninstall OneDrive completely, I don't believe its straightforward but I use a debloater script from Chris Titus: https://www.christitus.com/debloat-windows-10-2020/
Part of his debloater PowerShell script can uninstall/delete OneDrive

Problem I have with scripts and hacks is it may well work for say 4 or 6 months than the next major update Microsoft patches the hole or find way around it to than force their business model.
As Microsoft is now service business model now days. When Bill Gates and Steve Ballmer was running the show they where use to the old businesses model. That why windows vista and windows 7 was so clean with out all the bloat and adware.
