Yes, the fact that they phrased it as giving $100M in "free" credits (out of the goodness of their hearts, obviously, and not at all to try and hook new customers for their product ๐) did seem a little sus if their motives are truly altruistic. Structuring it that way really smacks of "we've built this so that when we're ready to start charging you for it, all we have to do is flip the switch".
