From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Somewhat. One, a system can be bootable without the entries because they are just pointers to the actual bootloader, so even if windows does the stupid and deletes them it isn’t the end of the world. It does depend on your specific firmware though.
Also two, you can write them again with a single line in efibootmgr, they’re just saying “if I click Fedora load the shim from the EFI system partition on disk 1”.
This is very different than the old world where windows would delete your bootloader entirely and the MBR couldn’t be easily explored. They live in the efi system partition instead - or at least the shim does- and typically every OS leaves the other ones alone (even Windows, except in this case, although it didn’t touch the shim itself).
The initial comment was about the bootloader and really only applies to MBR partitions.
