I don't quite see why Wikipedia articles should be changed because other webpages/services/apps use them for information... While I am of the opinion that infoboxes are very useful, I think they should list just the 'bare essentials'. In the case of someone who died young or violently, it can be wise to include the cause of death in the infobox. There was nothing particularly interesting/controversial about Chaplin's cause of death. The infobox does mention that he died aged 88, so most people probably already understand from that that he died of 'old age'. What really worries me is that if non-essential information like that is allowed to the infobox, other non-essential bits will be added as well, and soon it will be as long as the article itself...
