This is one side of the story, my thoughts on this was the fact that it was the platform that almost offered pirated software, form the OS, that for a long time only needed a serial number, and most software could be very easily found.
Up to a certain point thats true, but if the hardware is very old nothing can make it work.
True, and hopefully it would never do that.
Yes, for personal use, if you are in corporate environment that you will have to pay for support, but for personal use its 100% free.
Again 100% and if you are willing to give it time then you will learn even more things, but I said windows is offering convenience, and most people want that.
True. I dont like that much the windows10 theme, i would prefer the win7 look, but its not a huge problem for me.
Updates are an essential part of each operating system, and every one should have the latest security and software updates on their system. On the reboot part, well its not the end of the world for personal use, the problem was that with the first editions of win10 ms updated they OS, and decided that it was OK to just reboot, on all the previous version you had more control on how updates are delivered, and when you wanted to reboot the pc.
Linux has gone a long way, and nowdays its very easy to learn much easier to setup and also to use.
Also you can very easily to try it, and see if you like it, it only needs a DVD-ROM or USB flash drive to boot and work. As far as I know you can try it from window10 if you want learn the basics.
Everything has a learning curve, once you get pass this, you will be able to find what is better for you, OS X, Linux, Windows, what ever is best for your needs.
I dont think that auto update has anything to do with spying. Unless we are talking about android.
I am sure that many admin get very scary when they thing that they might need to restart a server, again it has to do with what you do, if its a server then restarting is not an options most of the time, if you are a PC user, then why not.
