The FTC shouldn't be bringing this case. VR is still up for grabs. Defining the relevant market as the "dedicated fitness virtual reality app market" is questionable, and the idea it "proves the value of virtual reality" is nonsense.

The idea that meta have some dominant position that can't be overcome is like suggesting Excite or Altavista had a dominant position in search that couldn't be overcome in the 90's, or MySpace in social in the early 00's. It's too early to call this market "won".
