They could, but they don't want to do that because they get paid by Google to not do it or because those actions get them money in some other way (from advertisers or whatever), or because they think only power users like some features.
By whom and on what basis? Those are non-optional questions that should have strong answers as preconditions to you posting about it, if the objective is to offer something more than simple bullshitting (in the Harvey Frankfurt sense of indifference to truth).
This also doesn't answer like 90% of my concerns from my previous comments. Who has ever intentionally had a software development approach of having one team develop features and another person revert those features, working in tandem? And why would they need donations that are 0.20% of what they already get in revenue to finance it? I feel like you're just improv riffing here.
