The man that did the heavy lifting to create the open source operating system would predictably have personality quirks (or even worse), we should just be doing what our ancestors did, make fun of him and complain behind his back (half-joking) but to cancel his appearances in which he'd discuss his professional career and thoughts on computer science, is throwing the baby out with the bath water.
this man is not a normal man. He's a brilliant programmer. We shouldn't expect everyone to be normal. He is the definition of fringe and weird.
