Remember when WhatsApp required a subscription? One of the first changes made by Facebook after purchasing WhatsApp was to make it available for free. And now they're complaining they can't milk it enough? Oh dear.
I know that a percentage of WhatsApp users would stop using the app if they started requiring a payment again –because apparently paying $1 per year for using an application on your $999 phone is outrageous, but I wonder why can't they just make it an option again as an alternative to ads.
