Because for some odd reason, the T1 Light Cruiser is different from every other ship type in the game, and doesn't really belong to any of them. It doesn't have cruiser commands, turns too slow for an escort, can't use science well, has no sensor analysis, and so on.
The T6 version is a straight up standard cruiser type ship. If they wanted it to use dual cannons, it would have had to have been made a battlecruiser, but it isn't one.
We had a dev explanation on Reddit. The T1 light cruiser can use DHCs because new players would get DHCs as drops sooner or later and they didn't want to let those new players be barred from using the stuff that just dropped, hence the T1 light cruiser has no class restrictions. The T6, as pointed out, is a default cruiser with no bells or whistles.
