Because most of them deep down know that yuri/yaoi gachas have such a small and niche target audience that getting involved or even attached to one is putting any money you spend at a massive risk.
It's best to get into omnipandering games where you can spend money safely and not be at risk of EoS a year later, and cope with minor interactions between male/male or female/female characters.
Case in point, the ONLY BL gacha game that existed [Noctilucent : Before Dawn] straight up went into EoS recently. Everyone laughed at them for it.
Yurifag games can 'exist' but they can barely skate by and exist in a permanent state of fear of EoS [See R1999, HI3, ect]
