definitely "not" fake news. even though the 1903 MCT was briefly available, MS has recently pulled the 1903 MCT as attempting to download that now shows a 403 forbidden error message and will be re-posted in late May.
I installed 1903 after using UUP dump downloader & UUP > ISO converter tools to create a multi-edition AIO USB install media (that has build 18362.53) on an old Dell laptop - seems to work okay.
But don't install the May 2019 update onto machines that use outdated AMD RAID drivers as I found out here.
Obtain the newest AMD raid drivers first and then try out the May 2019 update.
