I have used my Gmail box since early beta, and most definitely, a fraction of people I have ever contacted are no longer alive. There is no way for me or for LinkedIn to determine that. They may use an aggressive strategy to get new sign-ups, but that's just their way of shoveling money. Death is natural and inevitable, and I believe that we must raise people's awareness of it. I'd say deal with it and don't ever let the reality offend you.
Here is a good speculation from xkcd on a related topic: https://what-if.xkcd.com/69/ With it in mind, how valuable would a database of the deceased be in 100 years from now, if we start gathering this data today? For example, mining the internet for history on relatives would probably become a business of it's own, and as a consequence, ancestor's deeds would be much less romanticized than they are today.
