Copyright?

[Finii]

Did you even read the license of Cascadia Code?

But you

• Removed the Copyright: Microsoft (in the fonts)
• Removed the original license file which
  • contains the Microsoft copyright claim
  • contains the RFN, that is NOT LIFTED of course

Edit:
If it would be possible to remove the RFN clause on renaming (what you do here), what will keep someone to take Caskaydia Cove, modify it, and publish it as Cascadia Cove? Nothing, as there is no (you pretend there is no) limit on the usage of Caskaydia Cove. But the RFN is there specifically to prevent people to publish a modified font under the original name.
