I remember when Whatsapp became a paid app, I can’t remember the details as I believe they varied by platform (iOS vs Android) but it was either €0.79 or €0.99, I’m not sure if one off or yearly payment, but it doesn’t matter.
I, as the “computer guy”, had friends and family asking how to pirate it. This is coming from SMS costing €0.25 per message (text only!) and also coming from people who would gladly pay €3 for a Coke at a bar that they’d piss down the toilet an hour later. It didn’t matter if it only took 3 or 4 messages to make Whatsapp pay off for itself, as they were sending dozens if not hundreds of messages per day, either images, videos and whatnot (MMSs were much more expensive).
At that moment I realised many (most?) people would never pay for software. Either because it’s not something physical or because they’re stuck in the pre-Internet (or maybe music) mentality where copying something is not “stealing” as it’s digital data (but they don’t realise running Whatsapp servers, bandwidth etc cost very real money). And I guess this is why some of the biggest digital services are ad-funded.
In contrast, literally never someone has voiced privacy concerns, they simply find ads annoying and they’ve asked for a way to get rid of them (without paying, of course).
I should say, I’m from one of the European countries with the highest levels of piracy.
