They're modmakers, not facebook. It's ok if they don't interact too much, i mean.. Come one, years making a mod and sustaining it.. Maybe they are tired of the 90% stupid ppl that are always saying "hey, your mod broke my game" without a crashlog or "hey, can you add *insert Op stupid thing which makes no sense at all here* please?".
And, besides, they have lives.. They have family, friends, they're not some kind of celebrity, we are grateful for their work,thats all.. if you can't understand, that's your problem. But you're not the center of the universe and they're not some kind of slave that works for your entertainment. Their mod is their property, if they don't want to make a public release, that's their decision and we are none to judge it because we are getting THEIR work for FREE...
