It moves process from "put any distro and just install it" to "open the bios, find the right options to change or disable and then you can actually install it".
Why would this even have to be the case? Linux will work on hardware with a TPM chip. It will also work on hardware without a TPM chip. If you're saying one day, some distro may choose not work on hardware without a TPM chip, take it up with that disto (in your imaginary future)? It's not Microsoft's problem?
