It's not a fair remark though, all it did was twist what I said into a inflammatory derailment.
The point is there are a lot of (usually technical) people who are too focused one aspect, but are missing the bigger picture. If you follow them, you'll probably get a communication app that only those people can/will use, which has deal breakers for mass-market adoption. And once that happens, those people probably won't use it either, since they want to communicate outside their group.
