I'm concerned that they quickly removed the .deb. surelythey realised this would happen? It can't be news to them. The deviced has no way to stop you copying files from the filesystem. Locking against IMEI will just be overridden with LD_PRELOAD=fake_imei.so ./game
The store purchase for the 90ish% of non-technical people who don't forums or know the cmdline and just want to pay for great software, should be adequate to make money from honesty and the vague security by obscurity.

The fact it was removed worries me that they didn't know! I'd hate to not have any commercial apps after this untl they tie some amazingly complex kernal blob which locks you with imei and a non LD overridable system call (or something like that).

On a different note charging $3 to americans but almost double that to brits (£3) is completely evil behaviour.
