It makes a lot of sense for Apple to acquire Roblox. Based on what Matthew Hall wrote ( https://www.matthewball.vc/all/applemetaverse ), Roblox is operating in the grey area of the Apple store ecosystem. Apple would face a huge pushback if it banned Roblox from its Apple store. However, if it does not ban Roblox from the store, it will face pushback from other game platform companies that are not allowed on the Apple store. Acquiring Roblox would be a perfect solution that resolves this. Also it would put Apple into a moaty brandy family friendly ecosystem that IMO matches Apple's brand and company culture.
I am going to predict that Apple won't buy Roblox though, since Roblox is likely to be very expensive and Apple is quite conservative with acquisitions. Plus Apple infrequently acquires software or gaming companies.
I think that the likelihood of another company acquiring Roblox is low since Roblox is likely to be very expensive and there is a risk of Apple banning Roblox on the app store.
So although I think it would be a great match for Apple, the highest likelihood is that Roblox will not be acquired.
