In the past, Mojang has been somwhat laissez faire with clones of Minecraft (or otherwise games inspired by Minecraft). However, it seems like that's changing, with many developers getting emails from Mojang requiring the removal of any Minecraft-related content they might have published.
We have started to get emails from smaller developers, telling us they received takedown notices from Mojang and asking if they are real. All of these emails come from enforcement@mojang.com, usually sent by 'Karl Lowry' (who does in fact work for Mojang).
The developer of 'Minetower', Gamma Production, forwarded the take-down request Mojang sent him to us:
As seen in the above screenshot, it's pretty obvious the app is riding on Minecraft's brand. The developer also sent us this, sent exactly a week later:
The game has been removed from the Play Store, as indicated by it's current link. A cached version of the page can be seen here, but it will likely expire soon.
We have had several other developer send us similar take-down requests, which seems to be an indication that Mojang is ramping up take-down requests. Maybe Microsoft wants to protect the brand it payed $2.5 billion for, who knows.
