This is so disappointing to hear. I hate immersion breaking stuff and this sounds like the ultimate immersion breaking possible, with these avns and the characters being brought up a lot.
I am okay with subtle references, like when games have them on a TV or laptop screen, or they have, a line or two, but the way you are describing it, sounds awful and just bad.
I hope the dev sees these posts or someone brings it up and he changes it, or tones it down a lot, but not holding my breath, it's just sounds so stupid, kinda lost my motivation to play this update now, skipped last one to build up content, now this, guess I will skip this update too.
