My point is to reply to "State your case that bloat is good" with a famous blog stating a case that bloat is good. Bloat makes the company more money by allowing them to develop and ship faster, bloat makes the company more money by being able to offer more features to more customers (including the advertisers and marketers and etc. side of things), and - well, read the article.

I, too, dislike slow websites and web apps, but I don't think they are some mystery - natural selection isn't selecting for idiot developers, market selection is selecting for tickbox features and with first-mover-advantage they are selecting against "fast but not available for another year and has fewer features and cost more to develop".
