Why not? It's free.

This is from the Stockfish Wikipedia entry, emphasis mine:

  *Stockfish versus AlphaZero[edit]*
*  In December 2017, AlphaZero (developed by Google's DeepMind division)
defeated Stockfish 8 after just 4 hours of self-play, with no access to
opening books or endgame tables, but with superior computing power
allocated to AlphaZero.[26][27][28] Each program was given one minute's
worth of thinking time per move. In 100 games from the normal starting
position AlphaZero won 25 games as White, won 3 as Black, and tied the
remaining 72.[29] In a series of twelve 100-game matches against Stockfish
starting from popular openings, Alphazero won 290, drew 886 and lost
24.[citation needed] The results of the tournaments do not indicate that
Alpha-Go is a superior chess engine - the Alpha-Go algorithm was allocated
more computing power for the games.[27] Google said they are not commenting
on the research until it is published in a journal.[29] The research also
has not yet been peer reviewed.[29]*
