Migration of the account to a microsoft account

Hello,

The last version of the Launcher oblige me to migrate my mojang account to a Microsoft account.

My Mojang account is note a Microsoft account and I refuse all Microsoft licenses, that is why I use Linux.

Could you please show me the terms in the License when I paid the game that show I will be obliged to migrate my account to Microsoft ?

In my opinion it is a BUG because that feature in your Launcher is disrespectfull toward the license I agreed when I paid the Game.

Could you please fix this bug ?

Thanks
