A lot of tedium is added into these games to force the player into spending real money for skips & access to content. It is a valid way to incentivize customers into paying for given service, but also means there are many time wasting repetitive tasks that can ruin the experience if one does not grasp the concept of "when the game starts getting tedions, you are supposed to pay"

You're very much off the mark there. That may be true for gacha games or similar slop from the 2020s, but Runescape2/OSRS never had any sort of pay to win, or pay to skip the grind. Neither did WoW for instance.
