They blacklist some bootloaders, but it takes them forever. CVE-2023-24932 (from May 2023) had a fix available a year later (June 2024), had the update broadly made available through standard updates in 2025 (2 years later) and doesn't automatically install it today.
You might think the 2025 update will solve the problem, but:
> Before following these steps for applying the mitigations, install the Windows monthly servicing update released on July 8, 2025, or a later update on supported Windows devices. This update includes mitigations for CVE-2023-24932 but they are not enabled by default. All Windows devices should complete this step regardless of your plan to enable the mitigations.
The current status for the update (https://support.microsoft.com/en-us/topic/how-to-manage-the-windows-bo… says:
> The Enforcement Phase will not begin before January 2026, and we will give at least six months of advance warning in this article before this phase begins. When updates are released for the Enforcement Phase, they will include the following:
Basically, unless your company and sysadmin have enforced this fix (i.e. you're a home user), Microsoft hasn't revoked their keys.
Then there's CVE-2024-38058, a similar attack. Microsoft tried to roll out a fix, but that broke compatibility, and the fix was then rolled back. Again, that problem can be fixed with…

> The fears are legitimate.
They're really not.
First of all, no data is really lost with Git. Commits can be recovered from the reflog if they haven't been garbage collected, and there are ways of recovering anything on GitHub as well[1], even if it technically shouldn't be the case.
But this aside, data loss is circumstantial, like you say. I've heard the idea that force-pushing in general is harmful, when it's really not if you're working solo or on an isolated branch. Rebasing and force-pushing are just different tools in the toolbox.
In general, my objection is to the practice of describing any software as "dangerous". It creates an air of intimidation that prevents people from using the tools to their full extent, which when spread can popularize wrong practices among new users as well. This is why you see the person in the article claiming that they've always been a "merger", having a false dilemma between merging and rebasing, and describing their solution as "fearless". This line of thinking is also commonly associated with the command line and Linux itself, and is just harmful.
Instead, users should be educated on what the software does, which does require having comprehensive UIs and documentation, and designing the software with sane defaults, fail-safes, and ways to undo any action. Git doesn't do a great job at all of these, but overall it's not so bad either. What really hurts users is spreading the wrong kind of ideas, though.
