It's more that most slots go for high volatility these days, a lot of the rtp is in the higher wins, which means less smaller or medium wins that are possible. I think this trend is hurtful for the industry long term, many players will burn out a lot quicker than they used to on more survivable slots. There is definitely a need for a more balanced approach by suppliers, not every slot needs to be all or nothing (slightly exagerrated, but still).
It's also harder for casual players to find more survivable games, even themes with cartoon dog homes, or pigs being abducted by aliens are high volatile.
Operators are missing a beat by not being more clear on the type of experience a player can expect. Short term the gains are big, but life time value of casino players is surely down compared to a few years ago. Not only because of high volatility, but a contributing factor for sure.
