Your missing the point on the fact that IRC is all text. All you could ever do send links. It worked but sucks from now future on.
Nowadays where do you host those links? Github? Sure. But the FAFF of setting up a github static wank account. find some lets encrypt cert bot owned by google which expires every six months. Your going to do all that for one IRC Link?
In the days before tumblr, the simple days of MSN/Yaho. When IRC was active and flourishing. You could just send a link from your own server, a server in your bedroom. Sitting on your home 56k IP on a http server without needing any cert, any annoying messages, cookie banners to a user.
Those days are over. I know, but it hasn't gotten easier. IRC it's sitting right there, the diamond.
There is no need for TLS if you don't want it. Firefox and Chrome don't show a nagging window if your stuff is only reachable via HTTP. Have you even tried that?
