This is a no win debate because some people out there are more Hasbro fans then they are Transformer fans. If Hasbro buys the sesame street line, they all start collecting Big Bird. If Hasbro sells the Transformers franchise tomorrow, the sell their collections and roll with Hasbro like some fake ass corporate zombies.
This is insulting to people who prefer official TFs. You're calling them zombies and belittling their love of the franchise because you don't agree with how they perceive the franchise. Without any provocation too.
So, either you actually believe this, and don't understand other people's point of view, or you do understand it and choose to insult them.
However I honestly dont understand the position of "Pro-Hasbro" Transformers fans who are "Anti-Third party". I know you are not one of them, however maybe you can shed some light on what makes them tick...
Well, it's pretty easy to understand people who are pro-Hasbro and anti 3rd party (and bear in mind not all people who are pro Hasbro are anti-3rd party).
Hasbro (and Takara) made the Transformers. Regardless of whether you agree or not with this statement you cannot question that the vast majority of people see this as true. So Hasbro (and Takara) hold a place in people's hearts as the people responsible for the franchise the care about.
3rd party products, essentially, ride on their coattails. Their entire business model is build on people recognizing their toys as updated / batter versions of any given Transformer and buying them. But these companies; they didn't create Optimus Prime or Megatron or ANY of the characters they're using as a basis for their products.
Essentially, they're befitting from someone else's work. And the people who did do the work aren't getting any reward for these new products. Fundamentally, they see this as unfair. And it's an unfairness to those who created something they really care about. And this is where dislike can set in. Company A is ripping off Hasbro's (and Takara's) characters and some people just aren't happy with that.
And there's also a segment who feel that the 3rd party market as a whole is a ripoff. That the toys just aren't worth what they're being sold as and that they, as consumers, are being ripped off. These people thinks TFs of all striped ought to be sold at retail prices regardless of who makes them and that anything more is a ripoff.
And there are others who are indifferent to the 3rd party scene. Regardless of your point of view Transformers is a brand, and that brand is owned by Hasbro and Takara. It's not right to say they are Hasbro fans. A fan of official TFs may not care at all for Star Wars or My Little Pony, which are other Hasbro products. They are fans of the FRANCHISE. 3rd party products fall outside of their area of interest. Yes, Giant (for example) looks like Devestator. BUT we all know he's actually not Devestator. To fans of3rd party products this doesn't matter. But to fans of THE FRANCHISE it matters a great deal! To fan of THE FRANCHISE TFs are limited to official products (of which there are a great number).
The transformers FRANCHISE includes things like the movie, Cybertron, Animated, Classics, G1, etc. It does NOT include 3rd party products like Giant or Hegemon. Giant and Heg may be modeled after TF CHARACTERS, but those products do not belong to the Transformers FRANCHISE.
There's many reasons to limit yourself to the franchise. Primarily, for completionists, there's an actual, definable, goal. You can, for instance, aim to collect all toys from the Cybertron line. You cannot really aim to collect all 3rd party products. I mean, sure you can aim to collect every Fansproject toy ever made, but where's the line for the 3rd party when you have Shapeways kits, sticker sheets, and privately made kits made by individuals? Some products aren't even readily available to us (like Eagle's stuff). There's not a hard and fast line with 3rd party products where you can say you're collection's definitive.
This is not quite the same as dislike. To dislike involves a strong feeling. This attitude is more like apathy. Although I can see how such people can begin to dislike the scene when things they care little about overwhelm (unjustly, in their mind) the stuff they do care about.
And of course some people cannot afford and, therefore, hate. Some people are like that.
This is not really a debate. I am simply explaining reasons I've seen from people who dislike or are indifferent to 3rd party products. Stating disagreement is counterproductive. Obviously you disagree. Rather, this is what other people think and it's best to just kinda see things from their point of view.
This is really getting away from the point of the topic; explaining the legality of the 3rd party products, which is pretty helpful to know. So I don't want to get too involved with debates, especially since I'm very much pro 3rd party (although I am also pro-Hasbro/Takara).
