You're submission history here is heavy with Zcash-related links.

It's open source. If you think someone is writing malicious code, take a look for yourself. If you think the developers are no good, fork it.
He never lied. He made an announcement, and he was right about it being major, as evidenced by the speculators' reaction and posts on Reddit. Deflating the bubble before it gets even bigger is good in my opinion.
Right after that announcement, there were a lot of brand new accounts and accounts that didn't have any Monero history in them posting in the Monero subreddit. Supposedly, there was even an account or two that just had Zcash post history.
I think Monero is just fine, except for the opponents of Monero that are misrepresenting the truth (creating new accounts on reddit to fake outrage, companies with competing privacy coins posting BS reports about Monero on the day of routine hardforks, etc).
If you think something is wrong with Monero, you're welcome to join the open source project and help fix it.
