They just don't have any DRM on the client, but to answer your question in the past people didn't call it piracy, they called it not using Minecraft with a premium account.
The only reason we do now is because Mojang and Microsoft removed the ability to play the demo mode from the official launcher (which is a piece of garbage by the way) and told people they needed to pay to play Minecraft. Unfortunately a lot of people are neoliberals and they take that advice to heart and consider it wrong to violate those wishes.
But I do agree with you that they shouldn't I only do it with the display name of my community !minecraft4free@lemmy.dbzer0.com because it largely keeps the whiny neolibs who would whine about piracy away from the community.
