I think a clear distinction to make might be:
“Tech” as used in this sense is the industrial complex around mobile and web technologies dominated by a few players who might just be evil.
“Technology” is, of course, everything you mentioned and more. A rock that fits nicely in your hand becomes technology when used to crack a coconut.
It’s a weird linguistic murkiness, isn’t it?
It will be me. You have freedom of speech. I am also free to ignore, mock or ostracize you if you spout hateful nonsense near me.
