You forget that no sane webmaster or company is going to break the functionality of their site and lose most of their users. IE is still the most used browser and will stay so. Ideologically your thinking is nice, but its not going to happen anytime soon.

Except Firefox addons are not *necessary* to use any commonly accessed websites (AdBlock Plus and NoScript may be desirable, but not necessary). As such, the people who install them are expected to be aware of potential incompatibility and can disable them if needed (for example, if AdBlock Plus blocks critical elements of a site, you can whitelist the necessary element, or just disable it on the specified site). The required knowledge level to install an addon usually means they know the basic troubleshooting needed to fix addon related problems.

If Google decides that a large number of its services require Chrome Frame, people without the necessary knowledge will be installing it to use those services. And unlike the Firefox addon users, most of them won't be competent enough to troubleshoot any problems that arise from the combined renderer, or even understand the source of the problem.

In addition, it would not surprise me to see a number of sites add the metatag without realizing the implications. Too many web developers are hacks, copying any pasting random junk from forums, reading tips out of guidebooks without understanding the context, etc. If their site's JavaScript is too slow, and a forum post says "Add this metatag to improve JavaScript performance," they'll add it without checking to see if their page is Chrome compatible.

And exactly how would royalties from copyrighted works benefit his daughter? That the rest of his "estate" was able to so effectively wipe her off the face of history using the copyright cudgel seems to invalidate your point entirely.
