I realise I'm replying in context of Sir_Cmpwn specifically (and I have had my own interaction with him in the past on unrelated projects in very sour taste) but it is more common with anybody that promotes an apologetic-but-contact-me attitude. It's an all to familiar trait of people trying to sound good in threads of their topic.
"I'm sorry for making you feel that way."
That's very close to the classical non-apology apology "I'm sorry you felt that way". [1]
He isn't sorry for his behavior, but sorry that his behavior caused certain feelings. The post he's responding to doesn't mention any feelings, so I assume he meant "Sorry for making you feel that you were pushed out of the scene". He's shifting the focus from his actions (for which he is responsible) to other people's feelings (for which he is not responsible, since he can't control other's feelings).
"If you want to talk, my email is in my profile."
Meaning: Please don't continue talking in public about this.
"I was a jerk the first few years I was involved in the Minecraft scene, and I'm still a jerk all too often today." is the longer sentence preceding it which is 100% a statement about his own behavior. "for making" actually makes the sentence you're quoting about his behavior too, in my interpretation of it.
It's an apology. Maybe you don't think it's a strong one, or a sincere one, or one backed up by corresponding action, but it is one acknowledging damage done, some responsibility for it, and stating a desire to change (unless you have a wildly different interpretation than I do about what, exactly, "I'm still a jerk all too often today" means.)
We should all so this more often.
