Were does the funds of all these coins listed goes to
Most of the money from proper PoW coins goes the the electric companies and hardware manufacturers.
Really it's open and clear that whatever that's have advantages, in another form also has disadvantages, so in this scenario what is the disadvantages of who are coin developer?
Your list needs a better classification, and from there the dev/creator advantages derive:
[1] proper coins
The main advantage of the creator is that he can
mine early a number of coins, which, if the coin is successful, will hold great value in 10-20 years. Of course, many others will mine with him, just because they've paid attention.
In time, the dev/maintainer may get funding for his project.
If the coin is successful, he becomes a public figure and will go for various speeches here and there (and probably not for free).
[2] centralized, IPO, pre-mine coins, coins with developer fee
The creator will have a big amount (up to 100%!!) of coins from second 1 that he can sell and he can also manipulate the "emission" and the market too, hence manipulating the price.
[3] coins with developer fee
The creator will accumulate coins from every mined block. Coins he can use in various ways (see [2]).
[4] fork coins
The history shows that the most advertised fork coins were made by people having already big amounts of Bitcoin.
So they've got in their pockets from start that amount of fork coin to use (see [2]) plus the amount of Bitcoin they'll also use for advertising their coin.
All in all they risk their Bitcoins to create and advertise something else in their hope for supremacy, power, ... (and, sadly, it partly works)
