The original Minecraft EULA did not have any of the usual boilerplate language to support unilaterally modifying the terms. I had a Minecraft account purchased under this original EULA which was modified a year or two after I bought the game. Around 5 or 6 years ago, Mojang emailed me about changes to their login system that would require me to migrate my account to Microsoft’s system (no doubt under new T+C), but the migration process never worked and they never responded to my support requests.

When I tried to resolve it a couple of years ago I received boilerplate emails informing me that the migration period had ended.

So if you deal with companies that simply don’t honor their contracts—companies like Microsoft and Mojang—you don’t even need use to imply consent, because they can just lock you out of your purchases and tell you to pound sand.
