so shouldn't we be protesting against the systems that are locked down, instead of protesting against largely non-problematic implementations? For instance, with secureboot you can load your own keys, and the TPM isn't some sort of coprocessor that has access to your entire system.
>If Microsoft or Apple decides they don't like you or your app, all they need to do is to revoke your signing certificate, and Defender and Gatekeeper won't let your software run on Windows or macOS.
I'm not sure about gatekeeper, but at least on windows smartscreen can be disabled. I understand how having a gatekeeper sucks, but I also understand the problem of malicious software, which gatekeeping partially mitigates. In the end the fact that you can disable makes it a non-issue for me.
This is what Android has taught us.
Also, smartscreen is not a naive block of unsigned code. Code blocking is reputation based, and people disabling smartscreen and running a binary contributes to that reputation. Which means that people like gp are actively helping by continuing to use Windows and running safe-but-unsigned apps. So, to reiterate, not an issue.
