From the page's comments, and from WHAM comments, I can see that people who are hostile to that measure don't get the point :
- It's not about blaming people for using IE7 (it's not against customers), it's about the huge amount of time and money spent in making stuff compatible with IE7 (the issue rests on industry's side). That time and money are wasted for no reason, as: 1) Users could just upgrade to IE8 or use other browsers, 2) There is no good reason for IE7 to sabotage most standards except for the lack of interest of MS into complying.
- No need to use cutting-edge tech to experience compatibility issues on IE7. It ignores even some of the most basic W3 recommendations.
So, rather than a punishment, this tax is an incentive for people to just stop using a faulty product, that causes more issues that it offers services.
PS: Being the statist that I am, I'd rather have the government make companies pay for their choice of imposing obsolete technologies to the rest of the industry. Just like there are standards on cars driving on the streets (they have to be homologated first), there should be the same on Web Browsers: No standard compliance = no import authorization -- or higher taxes for those who use them.
