You're interpreting the title as "a static HTML page with password protection", but the way I understood it is "statically hostable version of a static HTML page with password protection", which seems to be exactly what this implements. I'm probably biased because I would have frequently had use for this, and all the paid offerings mention "private hosting of static pages", but I feel you're a bit uncharitable with your interpretation.

If you want to just have a free small private static page which is easily updated by public CI offerings this is a great solution, and the title transports this clearly.
