I think you have it backwards. Devs are not beholden to the tags on the game threads. The game thread tags are beholden to the content in the game. If a game isn't properly tagged, that's the fault of F95, not the dev. This is a piracy forum, first and foremost. Many devs choose to engage with this website as a way to market their games and drive engagement with their fanbases, which is great. But there is an attitude of entitlement among many around here that devs owe something to a bunch of people who pirate their games.
In any case, proper tagging doesn't solve the problem either. Games with proper tagging, particularly NTR, end up with endless questions about "is the content skippable?" Devs are under no obligation to make *any* content skippable. The fact that some do is a courtesy for the snowflakes in the fanbase. Ren'Py already gives players the ability to skip content, so the fact that devs write code to make that process even easier is showing massive consideration to players. I know of one dev who has literally told people demanding the ability to skip content to fuck off if they don't like it because he was tired of the constant whining.
As for the warning about "losing subscribers," this is a refrain that I hear often and the funny thing is, it usually comes from people who don't subscribe to or support shit. I'm a Patreon supporter of AV and I was pretty unhappy that Eli got a breast reduction. Did I pull my support? Of course not. One thing that made me unhappy doesn't outweigh the 99 other things I love about the game. As a dev, I can tell you it's not possible to make everyone happy. Not to mention, there are development implications that start piling up fast when you try to cater to all people, all the time. It's just not possible.
In the end, it's up to each player to decide whether or not a game meets enough of their desires to continue playing or supporting. They can feel free to voice their concerns but no dev is under any obligation to change the game to address those concerns. If someone is unhappy that 95% instead 100% of their desires are being met, that's a person most devs would be happy to lose because they typically bring endless negativity to game discussions.
