There are many points you make which could well be true. There is also the well-worn issue of some fans potentially losing interest, once 'present day' Sophia has proper, penetrative, extra-marital sex. Many porn stories move on, becoming better & more erotic after such an event but given his recent form, it may be that the Dev doubts his writing skills & ability to carry this off sucessfully. Perhaps he should just accept that some fap-happy chappies will leave & let everyone else have a good story again. Others with more than an interest in wanking would then be more likely to sign up.
IMO, some tags for AWAM could be removed with hardly anybody noticing, such is the absence of their subject matter from the various story-lines. If the intention was to do something about them later, I wonder when that will be, as in, which decade of the 21st century? There's still, (for me & I'm sure others), a mystery around why the "male protagonist" tag hasn't been added, after several years of the "2nd MC" status & concentration on Dylan, even including his POV. Whether or not the young joint-MC distances himself from Sophia remains to be seen but I don't think that will happen, now that AWAM is fully incest focussed & looks set to contain little else in the forseeable future, for instance, in the years remaining before AI takes over the world. It's the game itself, or rather L&P, who's more likely to become distanced from the woman who's purportedly still a joint-MC but now has an "episodic" supporting role, i.e. 'what's going to happen to Sophia this episode?' & will it make any difference, or sense? Does Sophia ever activate her "Renaissance woman," professorially-educated, professional brain anymore? etc. Alternatively, does Sophia have any everyday common sense?
That last sentence concerning Dylan's appearance schedule being reduced is contradicted by L&P's statement on Patreon that he intends to bring Dylan's appearances up to parity with Sophia's, for those fans who want to play as Dylan, (I'm paraphrasing, he said "to play with a guy," subtlety suffering in translation but we know what was meant). That's great news for Dylan fans, who should be "over the moon" as it shines upon a posh San Alejo restaurant & for the rest of us, not so much.
