I personally consider Virgin a major TV platform, that does not mean that Sky do.

From the Cambridge dictionary:

more important, bigger, or more serious than others of the same type

Two of those three are subjective.

I’d be over the moon if SA joined because I could ditch my 6 monthly £20 Now TV subscription. I’m just not holding my breath (and for the avoidance of doubt I firmly blame Sky).
