Marvel films, which (like much of big budget Hollywood at this point sadly) at this point are infamous for their exploitation of cheap unorganized effects artists, are probably a bad example for something being "not shady".
HN actually discourages high engagement by having the front page items change fairly slowly (rather than algorithmically customizing them to each user), not making scrolling beyond that (i.e. pagination and the "latest" feed) any less awkward to navigate than it has been forever and actively preventing you from commenting too much within a given timeframe (which it doesn't actively disclose when you hit the limit). That's probably a bad example for something being "shady".
