@windigo Apparently, "StartCom is a company based in Eilat, Israel that has three main activities: StartCom Linux Enterprise (Linux distribution), StartSSL (Certificate Authority) and MediaHost (Web hosting)". I was not aware of this.
Personally I am passively (i.e. only where the labeling is easy to read and understand without going several steps in the production chain) boycotting Israelian fruits, vegetables and such, but I have yet to boycott, say, #Intel CPUs or - in this case - #StartCom.
