Heavy Handed?

Is it really heavy-handed to give users a slightly second rate experience because they use an out of date browser?

Me thinks not really... effort spent should be proportional to the size of the user base.

Just a pity they didn't go further and send any user of IE off to the 1999 edition and throttle their download to the 28kbps they deserve... 80% of the effort for 20% of the users.
