No it's not. If we were 9 days away from a human written version of this experiment then yeah it would be reasonable to conclude they were lied to, because a human written version would progress so much slower and steadier that it's very unlikely you hadn't made up most of your mind a week before merge time.
But it's not human written. It's months, perhaps years of work compressed into a week, where the machine can go from 'nothing is working' to 'everything is working' in a few days. There is nothing reasonable about concluding you must have been lied to when such a delta in such a short time is possible. And if people fail to see that, then perhaps the initial assertions about an emotional meltdown were not so far off after all.
