As some have said, there's no employment contract between Grab and the riders so it is within Grab's rights to cut in half if they want. It is also the riders' right to stop taking the job from Grab (for some reason called strike in the media for this case). If Grab thinks what they're doing is right and will benefit their company, then they should stick to their gun. Let's see if there are 'many thousands' that will take over the former riders place. I personally foresee though that Grab will either return back to RM10 or change it again to placate the riders.

u don`t forget that rider need pay petrol themself plus maintenance, sometimes they don`t have order. Hard earn, try do it, last time i also do this job as part time then i know how suffer to do that job.
