Whatsapp to charge annual fee on Andriod user

Rumour spreads that an annual charge of US 0.99 would be charged by Whatsapp, which is a brilliant, ads-free, fast and simple communication platform on mobile phone. Not to mention the charge itself, which I personally think very reasonable as compare to the capital cost of getting a smartphone and the recurrent monthly fee or even the money users may "drop" for no reason, the talking point in Hong Kong is "there are thousands of users showing their anger toward such business action".

Character of Chinese (Hongkonger)
Trying to explain the shouting in regards the .99 annual fee, the ultimate factor should be the inborn character of Chinese. Being a country developing from a weak communist party with plenty of social and external problems, generations of Chinese was born to survive and retain their family. While it can be a good thing to maintain a nice social bonding in family level, there is basically no trust and respect lie between Chinese. This then leads to the current situation where people won't respect value of invention by privating peoples' works and ideas.

When someone cannot appreciate Whatsapp as a nice little software (Chinese prefer criticising then appreciate, esp. to other races), they found no reason to pay, even it's .99.

When someone thought Whatsapp as a blood-sucking devil company / business like those mainland ones, they found no reason to pay, even it's .99.

When someone thought Whatsapp can be replaced by the marvellous mainland WeChat (of course it's free and I believe it's funded by the Central Gov as a way of monitoring daily communication), they found no reason to pay, even it's .99.

Shame to have such mindset, even shame to tell the world that you have such a mindset
In this incident, I can agree no more on one thing I used to appreciate Chinese - Subtle.
Certainly no one is happy when a freebies turn to be charged, however, the worst thing is only these people would yell  / shout / complain on FB or wherever public......for how much? for .99.

Other thought
Just realised another similar issue about the free 3G internet connection for previous keyboard Kindle. Yes, it's free, it's worldwide, but then some tried even to "share" the signal for other purposes (even some wise one expected that excessive users might be blocked or lead to the removal of such service).
Greediness.
