Do you have evidence that it was intentional?
Yes:
Releasing crippled miners without checking them first but claiming to be honest and have integrity doesn't fit. Either they fucked up, something they will never admit, because only Evan Duffield has the moral integrity to admit to that. Or, and that's the only remaining possibility: It was intentional. There is your evidence.
^ Look carefully. Do you see any evidence of intent?
Wrong. No one represented that it had been checked, nor promised to do so. The reasons for the forking of the repo were clearly stated at the time, and they did not include anyone stepping up to volunteer to do code reviews. There weren't even any real developers, until later, when the group organized to do so. No one was misled in any way at any point in the process.
