> How did Facebook corrupt WhatsApp?

Previously WhatsApp had subscriptions ($1/yr) and were proudly ad-free. Facebook scrapped subscriptions and is about to add Ads. WhatsApp also never shared your number with anyone; sharing your number with advertisers is undoubtedly corrupting WhatsApp.

Yeah, I actually paid for the 3 year subscription. Now I can't even see the option. It was a big differentiator in my opinion. Their logic was sound too - even at $1 a user they could make a $1bn a year. (Even in developing countries - because of the networking effect - people would have paid that modest fee.)
