They're probably hung up because it's making them look small-time. What do 37Signals actually do, other than generate a steady stream of blog posts for HN? They make some sort of dropbox knockoff, right?
TODO and project management apps for small business. Unfortunately their success has gone to their heads.
Rails was groundbreaking. Yes. DHH did something great but that's now 7 or 8 (!) years ago. Rails has aged, DHH showed often how opinionated he can be and that he just isn't perfect. And the 37signals products live primarily because of DHH's and Rails' reputation and not because there are outstanding (there tons of better Basecamps out there).
Still DHH is a smart guy but a Kevin Systrom who built a company, who learned how to build a scalable backend while starting this company and then sold this company after just 2 years for 1 billion achieved something special as well and this should be appreciated instead of ranting. This is just infantile and shows once again DHH's temper and lack of self-control.
