Well since it seems you are smart, i will make it simple for you,
Lets say
Your knowledge is low and you want to open a server, since you are not able to make something on your own, you should search for something semi-ready.
So you have 2 options, FANDC and Sunrise.
Obviously FANDC have backdoors as it is proved many times in the past, after he takes the money he will never provide you support, as again it is proved and posted many times from his customer in the past, and the price is much higher than sunrise's for what he offers.
SO
do not wonder why sunrise have so many users, and every week it increases his popularity and his users.
Its obviously the best solution for someone who wanna practice, learn or open a server.
Sunrise,FANDC or scripts is not mentioned to people, who can built something on their own.
Simple as that.
The big question that should wonder you is not, why this people spend money for ready "crap" as you call them packs, BUT why the fuck since his knowleque is below 0 they want to open a fucking server.
And the answer is quite simple, because they think that they can make tons of money from donations, but we both know that is not going this way.
And to be honest most of our users, don't choose us for the features that are included on our source's, but for our updates/fixes ( on daily bases) and our support.
