Obviously they want to sell balls, but in addition to that, adapting to a new ball is a skill that itself can be developed and is regularly put to test. changing the equipment that all participants have been used to in the previous years is a weird idea. Does the Italian Serie A use the same ball year to year? Do they use the same ball as the Spanish La Liga? Does either league use the same ball as the Champions League? Usually not. Top players are used to working new balls pretty regularly. It is part of the game.
