I think this is just the beginning, computational theft will become more and more common. The less trustworthy exchanges and online wallets could be using this as a skimming tactic.

Hopefully Facebook, Amazon, Twitter, Twitch, Reddit, and other global leaders in the online space that lease/sell ad space on their platforms are also now aware of this problem and have implemented server side patches to fix this.
