There are responsible engineering conversations, and then there's bitching and moaning. In OSS mailing lists we don't put up with bitching and moaning. Programmers are expected to have rational views, constrain their emotions and bile, not be knee jerk, make complete presentations of what exactly is the problem, and make productive suggestions about corrective action to take. People who don't know how to behave like a programming professional, and work towards solutions, are typically banned from OSS mailing lists.
So if a bunch of programmes are currently engaging Google in a responsible engineering discussion, that's wonderful. Power to them.
