That's the point, I think. I own my computer, which means I decide whether it lies. If I want to serve "This website only works in Chrome" when it's actually cross-platform, that's my right. I might want the client to open the page in Chrome automatically, and I would have more control over the connection if I could do so, but that control would be over the client's computer. It's not a question of getting more or less control in general, but of getting rightful control over my own property.
> both operators want not just control over their computer but also what the other computer can do
Are you saying that my demand to not have a server control what my client does is an act of control over what their computer does? Like if I told you not to use your forklift to take my stuff, I'm asserting power over your property?
> Are you saying that my demand to not have a server control what my client does is an act of control over what their computer does?
Yes. The owner of that computer does not want to serve your requests and you want to prevent them from exerting that control over their computer.
>Like if I told you not to use your forklift to take my stuff, I'm asserting power over your property?
Yes that is what is being argued here. Forklift owners demanding the right to lie about using a forklift to property owners like Google who do not want to allow forklifts to take their stuff.
