Then consider the 1 second delay as an advertisement for consumer power. Google/YouTube annoys users with similar or even longer delays all the time. So I don't think you can see this as an "action against the user", unless you consider all non-user-tracking advertisements as an action against the user.
Also, the campaign can stop when Chrome and Firefox reach an equal user-base. So "the user losing freedom of choice of browser" is also not a strong argument.
Yes, it's sad that this seems necessary, but you can't fight corporate evilness with just goodwill. In a sense, this is somewhat similar to the paradox of tolerance [1].
