The lack of security on Minecraft accounts is a big problem with people getting accounts stolen. Migrating to Microsoft Accounts should be a good thing. Some speculation is this might allow skins to be synced between all versions of the game which might be a roundabout way of getting paid skins from the bedrock version of the game into java
@ArtificialWench But, from a more corporate view of the world, a good way of getting better data on the people who own the accounts and hard linking them to the machines they have Windows installed on so they either or both know how to sell you stuff better / sell you data for more to the highest bidder.
@ArtificialWench I might also note that getting your account stolen was not a big problem until Microsoft forced the use of email addresses with accounts in the first place...
