Binding arbitration WAS the new hotness. Some companies have learned that at scale it's a nightmare. Works for one case, falls over for 10,000 who refuse to bind to a single case and pursue the action, at your company cost.
The arbitration providers (AAA, JAMS, etc.) have also started implementing their own "mass arbitration" provisions. In some cases even providing subscription bulk pricing.
