$1 per stop is chump change for a company like Google. I don't see how this fee will create any difference for what the protestors are demanding.
And this type of fee reminds me of a Freakonomics article that talked about how a daycare started charging parents a late fee of $3 and it had an unintended effect of increasing the frequency of late parents, because it rid the parents of moral guilt for being late. In a similar way, despite the fee, the big tech companies are going to continue doing what they're doing, but now they won't feel as bad for it. I don't see how this solves anything.
