You do not own the OS. You didn't create it, and you don't even own a copy of it. You have a very limited license to it, as in permission to use it in a very specific manner, and no other rights other than those that you were granted. If you look closely even those rights may be subject to change, and change without your approval. Microsoft, under their current license, is free to do whatever they want to their OS, and as a for-profit corporation, their goal is to maximize shareholder value and return, not to create a pleasing product for you or your offspring. If you don't like the product, you should be asking yourself what type of incentive structures created it. And if you don't like that answer, your only real option is to do what you've done and use something else.
Once a company grows to a certain size, the wants and needs and opinions of individual users are no longer relevant. Users are more akin to cattle and only ever viewed as larger collections who exhibit certain traits and behaviors that can be channeled into profit directions (normally at the expense of other groups of users). Microsoft has decided that the experiences of those users is more valuable (as in generates more profit per unit economic) than the experiences of whatever group you fall into.
