lol what? Not only is that woman wrong but she's talking bullshit. Otaku are the main public of all of those medium for decades and sexualization exists at the very least since the 70s. It didn't had to have Evangelion for those people to exist and buy things, they exist since the 80s at the very least. Even on kids series, a huge part of it is bought in merchandise by otaku going from Pokémon to Precure and the same obviously is true with games going from Monster Hunter to Splatoon. They're on everything spending their money, not just in things with sexualization.
Aside from this, she and other still continue to insist that otaku need sexual things when there's hundreds of successful series without it or at the very least with something smaller which we can see in manga (which of course, it's always ignored in those arguments as the sales are much bigger than anime in units so a narrative can't be made), as well as those people aren't a hivemind that thinks the same and have different opinions. Shows like Yuru Camp, Zombieland Saga, Yuri on Ice, Idolize, Idolmaster SideM, Attack on Titan and other products that are very successful. It's not just because there's no sexualization or almost none that otaku aren't buying it. If there was no sexualization in any market.
And as anime basically exists as a medium for cross media for the main property since the mid 70s from other medium like manga and novels (later on, games, light novels, etc), anime is very dependent and influenced on the content which will be adapted to construct the medium per se. At the end of the day, what exists on anime from it's inception to this very day is by the majority of the cases, due to adaptations going from genres to designs to artstyle and stories as the quantity of adaptation per year is like 95% compared to original series. And of course, adaptations will exist because the companies involved want to boost every one of their industries and products, which is why adaptation is the majority, which is why there's funding for the existence of them and it's why there's 300 anime being made per year since the 2010s with huge or big japanese companies (or chinese like bilibili or american like crunchyroll) funding their creation in a committee system. But this is for another story.
"The more mainstream non-otaku Japanese games are probably mostly on mobile now."
If anything it's the contrary. Many of the otaku came to mobile and abandoned handhelds and consoles, much like franchises made the transition. Those were the games with more revenue in the market in 2018, which is yet again only behind China which is the first in mobile.

Aside from that, this definition of otaku is such a mess. If you say as an adult that you play Dragon Quest, people will think that you're otaku. Same for watching anime, reading manga or anything that is related. It doesn't matter if you're a man or a woman (which is why there's 45% of women out there). Same thing happens for teenagers where they will be called an otaku for doing the same things. Doesn't even matter if they call themselves one or not, this is what will happen. People really focus on otaku and sexual things but at the end of the day, otaku is basically just a definition for nerd in japanese with different people and tastes.
And not entirely related but it amazes me that people really ignores that japanese medium is probably the one with the most focus on female public out there, which is of course, also otaku. With manga, you have a huge bunch of manga from shoujo and josei magazines, in light novels you have entire imprints focused on female market, in games you have idol simulators with male idols much like it happens with men along otome games and so on, there's of course dramas and anime, which unfortunately the last is the only thing that seems to always matter in the west. lol But even in anime where the quantity of shoujo manga adaptations is low and josei is zero on pretty much all seasons, there's always adaptations of mobile games or just idol anime focused on girls like Idolize, Idolmaster SideM, B-Project, King of Prism, Starmiyu and others.
As for why there's few shoujo and josei manga adaptations in anime.. Aside from the fact that their magazine and manga are less popular than seinen and shounen ones, those mostly will get adaptations on dramas or movies instead, even more on the case of Josei. This is due to the fact that Josei magazines and manga are focused on women and the main buyers are women over 30, with many of them being housewives or working on corporations. Due to the public being much older and also because the stories are realistic for it's huge part of series, the investment on cross media is instead made on those other mediums, even more because the majority don't like to watch animation.
