The Pro SKU for Windows still exists and does offer more options for Update control.
Even if your OEM won't sell you a Pro edition license, it's also easier than ever to move a Home SKU to a Pro SKU because it's a one-time $99 purchase in the Microsoft Store and an in-place software update.
Windows 10 Pro offers more options for controlling things like updates and telemetry than Windows 10 Home, but it still doesn't meet the minimal acceptable standard, which is that the user can decline to install any update they don't want and can turn off all telemetry.
I think we definitely disagree on what a "minimal acceptable standard" is here.
Declining updates in general weakens herd immunity.
Pro does let you turn off the "Basic" telemetry that is mandatory on Home and that turns off "all" telemetry in the OS itself (you may still have to opt-out for some applications). Keep in mind that turning of "Basic" telemetry also turns of Windows Error Reporting and crash/BSOD telemetry, which can also weaken herd immunity.
Anti-telemetry and "update control" arguments kind of sound a lot like anti-vaxxer arguments.
Declining updates in general weakens herd immunity.
No, declining security updates that are applicable in your situation and that actually work weakens herd immunity if the threat is contagious.
On my system, I'll be the judge of when that applies, not some external organisation, and certainly not an external organisation with a track record of both abusing an automatic update mechanism to push changes that their users don't want and pushing changes that break things.
Anti-telemetry and "update control" arguments kind of sound a lot like anti-vaxxer arguments.
Anti-vaxxer arguments are not grounded in science and evidence. They advocate not taking effective preventative measures by denying the existence of the harms those measures prevent.
Given that the risks from both bad updates and data leakage are well established, if anything I'd say the argument that we shouldn't care about controlling our own systems and uploads from them is the one analogous to anti-vaxxer reasoning.
