Here's the history as far as i know,
Insomniac was hired by universal studios (yeah, THAT universal) to make three Spyro games, no more, no less. So when it came time to make the third, they worked harder than they had with the other games, making it one of the most fantastic games on the ps1 library. But after that, they couldn't make any more games with universal, so the Spyro IP moved around to different companies, resulting in sequels, retellings and games that i generally don't like as they divert from the classic collect-a-thons. And then toys for bob comes into play.
They purchased the ip and made the Skylanders series, using Spyro's name as a way to draw in fans. The old fan's beef with them is simple, Skylander's presence siphoned away the chances of a remake, as they realized selling overpriced pieces of plastic separately was an effective business strategy. Now that skylanders is selling less and less items, they're turning to their old franchises and remaking them, to recoup some losses. It is this reason that I believe is why they're remastering crash, and medEvil, and eventually the classic purple dragon himself, which is what we want.
