I can see the sellout aspect. Seen it happen myself with hentaigames, about.. 5 years ago most people made games with a passion and for free, now there's a lot of demo gibbe money plz patreons games. They are obnoxious, and they might inspire creators that would otherwise make better, free games, but that is hard to quantify.
Depends, I would agree that there are a lot of people that just do it for money. But there are also people that just love doing this and if they can turn their hobby/love into something that makes money, then kudos to them. It all falls down under not forgetting why they are doing it. As soon as they do, it's just pure money making.
On the other hand, if you have a product/business that isn't generating positive revenue, it's a failed product from money making perspective, yet it may be a proper product from other perspectives. Depends what it is and what it was supposed to do, it's initial purpose.
However, the mistake you make Yoshi, which Pedoune points out is that you assume that the existance of something negative must also mean the nonexistance of something positive. The only reason you think so is that your knowledge of the scene is, by own admission, very shallow. That in itself is not a problem, but you making generalizations and judgements based on it is. You are slandering a group of people based on the worst example of them, leading you to remind me of these people:
You must be registered to see the links
I am not even going to bother watching that video

But you are right, I assume that's how it looks, with all information I have right now, as I don't care as much about cosplay scene to check. Then again, you are wrong that I don't expect anything good from that scene. Problem is, when we talk about issues, we look at bad things that need fixing, not good things that don't, unless scale is so small, it doesn't really matter. If it's not broken, don't fix it.
I should have probably pointed out what's obvious to me, so it doesn't need any extra explanation.
So again, I do think that most female cosplayers are just attention whores, which already indicates that there are positive aspects to it (#notall kek). What I may have gotten wrong here, is scale, maybe it's other way around and attention whores are just a small part of the cosplay scene. Whichever way it is, attention whores are definitely the group that you can see first when checking cosplay, so that may paint image of a lot of cosplayers for people that don't care as much.
Small and loud in-group with negative aspects will always have negative impact on the whole group for the people that aren't part or interested in such group.
I thought you were more fun, and less shallow a person to be quite frank. Ironically, by making your point and sticking to it, you start to sound like those you despise.
Edit for a quick TL/DR: There's still passionate cosplayers out there, I have no doubt, if you look only so far as the bad ones and call it a day that says more about you than them. Me, I just look for good cosplay-porn. Om nom nom.
Yup, definitely need to start making myself more clear.
Before anyone asks: Simple, don't give attention to attention whores, but don't silence/remove forcefully.
