Lets truly face it.
People aren't actually pissed off that you moved the shard.
People are truly pissed off about your knee-jerk reaction to 'issues' in game, while more important issues get overlooked, or straight up ignored.
Want an example? Bangkok and the very apparent issue with bots, spoofing, multi-accounting. If there's an issue with a city and you don't want to enforce your own rules, do not hold an event in that city. Did that perhaps ever occur to you? I'm guessing not, since instead of enforcing your own rules, you blatantly informed people you wouldn't be, and essentially threw the Bangkok anomaly.
Then you decided to take another shot at recently, while not providing any sort of solution that actually worked. Your Intel Mobile site is unusable. If I wanted to sit and wait 15 minutes while using up 10 megs of data (yes, I've actually checked this....it's pathetic) to check the map I could. Unfortunately, in that time I could have driven home and used my PC to look up what I wanted, and probably almost gotten to the portal I was looking for. Yes, it's true, your map is completely worthless without a true PC. And even then, it's debatable exactly how useful it is.
Now you felt the need to change the rules of engagement after some people found an ingenious way to protect a shard for a period of time. I can't think of a single game designer out there that wouldn't state 'interesting use of game mechanics', patch it in the next version, and continue on with life. Instead, you felt the need to completely change the gameplay there, and interrupt everything like 'the hand of God'.
When administrators interrupt the game like this, it only creates backlash, upset users, and will likely chase users off and definitely give you a bad reputation. I know I haven't been saying ANYTHING positive about this game anymore outside of the social aspect. I can imagine the many NYC players that are likely to either quit or flat out bad mouth this game will have a very negative impact.
I think you could really use a good does of 'think before you act'. It's obvious that you aren't considering that, and never have. Going forward, if you want this to succeed further, I would highly suggest doing that, before you do fully chase more of your loyal users away.
