this is not a very good defense for just about anything
It’s also how the internet works. I left it off because it was the subject of the comment. People didn’t flee those because of the advertising. People left because the internet is undeniably better by being larger, more convenient, timely, and is a 2-way comms channel. Advertising still drives everything there.
I use discord as my primary work app. If they add ads, I’ll likely move to something else also. And that’s the point. Platforms should be free to do whatever they want and consumers are free to react.
