I'm not a fan of NTR, but how much of a crybaby you have to be to request to remove such a scene... it has nothing to do with NTR, that is not the purpose of that scene.
It was always possible to avoid fuck Zaida. So it was okay if she did a blowjob for a random male character. There was no reason to complain. But basically half of H content in the game, up to v3, is with Zaida.
And if the player avoids Zaida, the obvious complaint that Dev would hear / read was that the game has few H content after X months.
Dev decided to change the opening scene with Zaida, because without the initial blowjob (Zaida + random male), few players will avoid Zaida. And then Dev's effort to create several H scenes with Zaida and MC, will not be wasted. Whoever avoided her, from the beginning, had few scenes to enjoy in the game. But now few players will despise/hate Zaida. Good move of Red Rocket, who doesn't want players to hate/ignore Zaida.
Who does not ignore Zaida, has enough H scenes in v3, to see good potential in the game.
