As do I, for personal projects/personal use. When my company needs to create a functioning website in IE7 for healthcare professionals because they have to use IE7 and don't have a choice in updating then it better work in IE7... My point was "if his target audience uses IE8 they should support IE8". It's a simple question for any dev to ask themselves and it comes with a simple answer. If you expect to sell anything or provide a service - your competitor that supports IE8 will win a number of your customers over by supporting IE8 better than you do. If you can afford to lose those sales to a competitor, feel free to disregard IE8. (It's often only a negligible amount of sales anyways.) I don't think anyone supports legacy browsers because they want to.
