So I just thought of a nice analogy to what is happening here.
Let's imagine a brothel with high quality women who all serve a special niche. So there's this beatiful woman with medium-sized tits and pale skin, just as I like them, and she's the best foot fetish whore of them all. So I regularly visit her to do foot-fetish related things that most people would probably find boring or even off-putting, but I enjoy it and she's really great at providing this enjoyment for me. Sometimes she lets me rip open her socks so I can suck her bare toes, sometimes she lets me smell her very aromatic feet after a whole day in leather boots, sometimes I just give her a simple foot massage and rub her soles in my face. And nothing of it feels awkward, because she likes it too and it's her specialty. We both enjoy it, and sometimes we also have a nice friendly talk rather than just the pay - have foot sex - leave routine. She's a woman with good looks, an interesting personality and she does exactly what I like, she has all a fetishist like me needs.
But then, she has to leave her job because her pimp says she doesn't make enough of a profit. Sure, she's high class and expensive, and she has a small following of loyal fans who are exactly into what she does, but it would be a lot more profitable to replace her with some big-breasted bimbo without brains who just gives regular fucks to people. So, for several years, the brothel only keeps big-breasted bleach-blonde bimbos with tanned skin and zero class. And the masses just keep coming, while those people with certain fetishes, or heck, just with different tastes like medium-sized tits and pale skin, they have to arrange private meetings with independent whores because the big brothels just don't serve what they want anymore.
But one day, that woman with the pale skin, dark hair, medium-sized tits and beautiful feet returns. The pimp brought her back because he thought she could be quite profitable after all. But I don't recognize her anymore - she has changed completely. What used to be a beautiful, refined woman with style and class has become something entirely hideous. The pimp took her back in, but he forced her to change in order to make her more accessible to the masses. Sure, she'll still do foot fetish stuff, but that just doesn't attract as many customers as other stuff, so she had to train some other skills extensively. Like getting fucked in the ass and giving blowjobs. But it seems that he has lost her passion, and doing foot fetish stuff with her just doesn't feel as natural and intimate as it used to. And her looks have changed, too. Her breasts, her cute little breasts, have been inflated to 400% their original size by cosmetic surgery, in order to "adapt her looks to the current times". Medium-sized tits are outdated, and the fact that her tits weren't gigantic before was just due to technological limitations of the times before giant-tit-surgery. Also, she surgically had a dick added right next to her vagina, "so she can attract a broader audience", said the pimp. But he assures me that apart from her new skills, her huge tits and the dick between her legs she's still the same woman whose feet I loved to worship all these years ago.
But she isn't. Everything that she had been was gone. Yes, you could still suck her toes, but it wasn't the same anymore. She'd always try to press her abnormally huge tits in your face, because the pimp told her that's what customers expect nowadays. Those tits always have to be shoved right in their faces. Letting your customers explore your body and discover what they like by themselves is too challenging, people just want to pay for a good time without having to do anything by themselves. Also, while you can totally ignore that dick between her legs and just focus on sucking her toes, it's just so horribly distracting. Yes, the pimp claims you can also do cunnilingus to her just like you could in the old times, but it's impossible to do it without that dick slapping in your face. The old fans are disgusted and the few women in the fanbase decide to offer their services for free to the other fans instead.
And while the women from the fanbase keep delivering the quality we always loved, with pure foot-fetish fun, untainted by any obligatory AWESOME things all whores are forced to do nowadays, the mainstream audience cums all over the "re-styled" version of the whore we used to love, oblivious to the irreparable damage that had been done to a woman who was one of a kind.
We will miss you, poor Garrettina. They destroyed you for the sake of reaching a broader audience, but we will always remember you as you have been. And the mainstream audience will forget all about you in a few years, when the new trend is whores with dicks surgically attached to their nipples and you're just not AWESOME enough for them anymore. But we will never forget that you had once been the very best in our particular niche.
