The question is – will sheer enthusiasm last for long?

I started the HotA project in April 2008. Now it's 2019, and February is coming soon. I won't judge whether this is a long or short time, but throughout the project's existence, there has never been a rational need for monetization. Well, if ideological and moral-ethical reasons are set aside at the discussion stage.

Well, of course, it's monetized. We're swimming in gold like Scrooge McDuck, and public statements about "strict non-commerciality" are all a facade, a smokescreen, and a conspiracy.
