I know some Linux distros already supporting enabled Secure Boot

It's not that secure boot nor the TPM in any fashion keeps Linux from inherently working. It's that it enables the OEM to decide what software is allowed to boot on the computer and enforce this.
Microsoft typically gives OEMs a substantial break and the OEMs in turn sell most SKUs to 99% windows users and make only a small margin on those devices. A small discount on the cost of windows could make devices disproportionately more profitable and MS might be apt to see a percentage in offering such a discount to help lock out the competition.
They have in fact over the years engaged in far more unethical behavior including investing tens of millions in a "partner's" fraudulent lawsuit/pump and dump scheme against various Linux vendors bankrolling an entire list of felonies.
