That's old stereotype, yet people so commonly make the mistake. They don't have anything against Linux or open source, based on any news about them in past years

That may be EEE strategy.
On the one side Linux is made available on Windows. But having dual boot Windows / Linux is incredibly difficult.
In my case, my BIOS looks for the Microsoft folder in the EFI partition. It ignores the EFI configuration. So even after installing Linux and having the EFI configured, it would still boot on Windows. I had to rename the folder in the EFI partition so that the BIOS would let it go and finally use the EFI configuration it was supposed to read.
In my case, I did non want to ditch Windows completely, simply to have the choice and of course progressively use Linux.
So I added in the GRUB menu an entry for Windows, because the existing one was not working anymore. So I had to figure what to put in GRUB config files and rebuild the menu.
I thought it was it, but as I started Windows again, it started to install itself in the EFI partition without telling me anything. By the way, Windows installing stuff all the time without asking permission, that's not ok. I guess I got at last some tranquility by using I don't remember what tool to disable the update, uninstalling the update installer and removing its directory in the Windows folder, and probably other things I don't remember.
At some point, Windows would not even shut down anymore. Clicking on the shut down would turn off the screen, but in fact, it was only logged off. Moving the mouse would show the log in screen. Had to keep the power button pushed to get a hard shutdown. As a result, that has destroyed some sectors of my hard drive and in order to read Windows drive while on Linux, I had to reset the NTFS partition a number of times.
So you see the two side of things: on one side you can use Linux within Windows, but on the other side, everything will be done to prevent you from dual booting and migrate towards Linux.
