Not all of those employees would be engineers, and out of those engineers, many would be backend engineers improving the speed and ranking algorithms. Apollo would also be taking advantage of that work.
Of the iOS engineers, many would probably have been working on priorities that generate money for the company, but we all hated. Apollo had a great model where he just had to make the users happy enough to give him subscription fees.
I hate the decisions the Reddit leads have been making, but I guarantee that the employees have been putting in plenty of effort. It’s the company’s priorities that are misaligned with what the users want.
