Seriously, if ever comment on this page containing the phrase "I believe" or "I think" was deleted right now, we would not lose any objective facts.
while googling, I found this page:
(warning, it's a 4chan thread, overflowing with hateful comments) https://archive.is/2Cdj1
In there, horrible people are inviting other horrible people to go on twitter and troll (i.e. harass) Ian.
If you're close to taking your own life, you want to be close to your loved ones, and the last thing you want is to get random people calling you names.
Really crushes my faith in humanity.
We need more people like Ian.
This sounds a lot more like 4chan trolls than it does one of the leading lights of OSS. I know people are trying not to speculate, but I wouldn't be surprised if his account was hacked. In any case, I think you can honor they memory of Ian and still try to find out what happened to him.
/pol/ was created as a containment zone for idiots because they were too much of a hassle on /b/ (the board where literally anything goes.). The only people taking /pol/ seriously on 4chan are the /pol/acks themselves.
