Xbox releasing smaller 1st games on the Switch isn't a problem for me because it will always be the worst playable version available and I have Gamepass anyway, I also think that games like Fallout 76, ESO, Diablo, Overwatch, Grounded and Sea of Thieves would benefit on being on the Switch 2.
If they begin to port upcoming AAA 1st party games on the Switch 2 (which would likely be impossible without a Cloud version) then I would begin to worry, But under no circumstances should they ever help PlayStation even by porting small titles.
