This article is awful. Dennis Pushkarev isn't holding anyone hostage. They have dedicated years to software they gave away for free. They want, quite reasonably, to be able to make a living, and so told people they can't keep working for free. For me the deal of open source software was I get the source for no payment, with no warranty. It seems some people get furious whenever devs stop wanting to give million/billion dollar companies high quality software for free.
