Re: Point
No, that's not how it translates because of two things I think you probably already know:
1. On an X64 processor, you don't need custom images of any operating system, and you usually don't need custom kernels either. On a Raspberry Pi, you definitely need custom images, and sometimes you also use custom kernels. On other ARM boards, you always need custom images, and you often use custom kernels. The more "custom" things you have in a build, the more annoying the process can be when something doesn't work as expected. For instance, in-place upgrades from one standard distribution to another are a pretty common test target and generally work well, whereas doing that with images sometimes breaks or just isn't available for a while, and if your kernel has patches which haven't been upstreamed, you may not get to update the kernel at all unless you can find the sources and try to patch it yourself.
2. If you really do want to run Windows, the Raspberry Pi can do it. Probably better now, because the last time I tried, it was on a Pi 3B. Windows 10 didn't like the single gigabyte of RAM and, while it ran, it wasn't fun to use.
If you insist on misstating what people say, you paint yourself, not as someone who understands the distinction and has a good argument, but someone who has a pointless adherence to a product without the knowledge to explain why. There are reasons to favor the Raspberry Pi, but you haven't stated any of them.
