Of course the average amount of ram in computers isn't some secret. What are you on about? It's only thanks to the fact that we have gigabytes of ram these days that inefficient practices are possible. If developers didn't know that, they would have no idea that was possible. How on earth do you think developers would ever optimise software and determine their performance requirements if specs were unknown? I'm not saying they're snooping on YOU individually (although there's a ton of telemetry these days everywhere and ram is probably a common statistic collected by software - Steam's hardware survey is public and shows millions of computer's specs. Any software you use knows your ram capacity - it's not secret. The ram capacity of newly sold systems is public is obviously shown on spec sheets)...
