Not being a big fan of regulation in general, but if you're going to regulate, should these companies be at the top of your list? There are plenty of wrongs being committed by a variety of companies and industries right now. Not saying these companies are as holier than thou than they preach to be, but they are all innovative and good companies. While they have practices that merit examination, so do many other companies that have histories of being far less transparent and far less proactive about change.
I don't mean to say the world of tech doesn't need a fair amount of reflection and self reflection, but this recent bandwagoning of "regulate tech!" seems reactionary and hype driven as opposed to more well intentioned. This guy was even mentioning his book... The media has covered tech in the last year in a "if it bleeds it leads" capacity that I think undercuts many of the valid points being raised. Idk, I could be wrong, but that's my two cents
