Because these goals are inherently at odds with for-profit software development. If you're a business who produces software, you must not only 1) charge money, but also 2) plan to charge more money.

Windows usage is broad enough that the "new users" revenue stream is pretty dry, but it's also hard to say "we increased the price to $X while making windows smaller".. so they will endlessly pump in new "features" and bloat.

I recommend using an operating system that isn't driven by a thirst for revenue.
