Bru I guess the game choice will be divisive as SNC was in TM2 this year. It did actually benefit NRL though as there are some new players as a result of SNC that wouldn't otherwise have bought the game and tried NASCAR Planet and NRL out.
Either way it's their competition to do how they see fit with. There are enough players in TM 2020 to make it work now but it's not something I will be bothering with.
Whether it's a good or bad decision only time will tell. I'm saying this as a complete neutral on the competition as it's not really one I have ever bothered with anyway.
If they made the wrong move they can always switch back to TMNF or TM2 in future so it won't really hurt to try it for 2021.
