Just answering direct questions.
QuoteAnd where did you get this information about him not talking to Technic/Tekkit at all?
Why would kaker keep it secret and lie about it? He hasn't tried to cover up any other author dislike, why would sengir be special? Why would sengir try to keep the code hidden when he could come out and say "My mod will no longer work in technic." and make his mod just crash not load instead of a certain part exploding.
There are no posts on the technic forums from sengir, and none of the trolls trying to fan flamewars have reposted sengir calling for technic to remove forestry.
Burden of proof. Defend your claim. Show me where sengir said something like "I told them to remove it but they..." because all evidence points to passive aggressive brooding and an attempt to defame the technic team by attacking their userbase.
If you can't provide that, then please stop repeating the same argument over and over.
