With all due respect, isn't it sort of easy and doesn't it somewhat suit you to say that you don't know what a computer has in it? That limits your responsibilities. We often hear telecommunications companies say that they are just a channel. Yet your ads are not about how nice or big the channel is, but rather on how fast downloading is, how many videos are available, and so on. You are using the content provided by the creators. You also say that you have no responsibility. I find that hard to accept. That being said, I am well aware of your technological constraints.
But I think, as a group, you have some responsibility that you do not want to assume .
