I predict that this will blow over, and won't be a big deal in a few years time once FOSS drivers for what is effectively just a new breed of TPM are released.
If in five years, it turns out I was wrong, I'll eat my hat. Although defining "my hat" by then might be difficult, as it'll probably be subscription based.
The trend for security in desktop computing that's pushed by these large companies is to, over time, approach similar levels of lock down that mobile devices currently have. Both Windows and macOS are approaching the iOS security model that depends on manufacturers blessing what software can run on their products, and banning software they don't want users to run.
For example, with Defender on Windows and Gatekeeper on macOS, developers need to buy certificates from Microsoft and Apple's partners in order to distribute and run their software on users' desktop computers. If developers want their software to run on Windows or macOS, they need to remain in good standing with Microsoft or Apple. 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. That, or they can choose to no longer renew your certificates after they expire.
