Because the comics and the show are made by different team. The comics had Sombra return, take over the Crystal Empire again, and then reform. Whether because they didn't want to rip off the comics or simply didn't want to see Sombra become good, the show team had him come back and stay evil until the end. Some fans-myself included-have made efforts to reconcile the two depictions, though officially speaking The Beginning of the End presumably retcons Siege of the Crystal Empire.

As for the latter question, you and I are not the only ones to wonder why that's the case. At one point the idea of Celestia and Luna's Alicorn parents was on the table, and the character who became Tempest Shadow in The Movie was originally conceived of as Celestia's brother. But for one reason or another, we've not gotten any male Alicorns-and we might never, given the upcoming series finale.
