Major part of it is that some people differentiate hard between rogue-likes and lites, and others simply do not, and the two will never get along with each other. The thing being that if there are any type of permanent upgrade/unlock systems that makes the game easier the more you play, it is not like rogue, where instead of grinding for more max hp or dodge percentage, you “grind” knowledge and experience as a player.

Which means that there are very, very few actual roguelikes because upgrade systems are just so cool ™ and every game obviously needs one. Or three.
