If they held the patent defensively, that would be one thing. But this is not that. They are suing Meta for damages. That doesn't happen unless Voxer brings it

If they held the patent defensively, that would be one thing. But this is not that. They are suing Meta for damages. That doesn't happen unless Voxer brings it to court. It's not like Voxer wrote the patents, sold them off, then is getting money because TrollCo is suing Meta for infringement of those patents. No, Voxer is suing. We can completely blame them if they are suing based on shit patents.
