The problem here is that due to how integrated the loot box system is to the overall progression in Forza 7, it will take some time to remove them. That is to say, the removal won't take place until the Winter update for the game.
Here is what Hartman has to say about this decision to remove the loot boxes.
One major area of discussion for the team has been prize crates. While we’ve never charged money for prize crates in Forza Motorsport 7, their presence in the game has continued to be a source of controversy. The overwhelming feedback has been that this system feels out of place in the game. After careful consideration, we have decided to completely remove prize crates from Forza Motorsport 7. Similarly, paid tokens – which were a part of previous Forza games – will not be coming to Forza Motorsport 7 or Forza Horizon 4.
Due to the complexity of removing prize crates from the game – while keeping access to Driver Gear, Mods and Badges – we expect that this process will be completed in the winter timeframe. Starting this month we’ve already taken steps towards that goal, first by unlocking more than 100 previously locked “exclusive” cars and, second, by completely removing cars from the prize crates in the game. The current lineup of prize crates offer no competitive advantage and only offer Driver Gear suits, Mods and badges, and these crates will remain in place until crates are removed entirely.

That's some fantastic news there. Ina ddition to this, the team is working to continue adding some new features to Forza Motorsport 7 including the usual bug fixes and PC performance tweaks. He also notes that the game has added in some new features like test drive for multiplayer, panning focus for the Photo Mode, better paint tools, and more. They also released some free cars from manufacturers like Porsche, Honda, and Ford.
