But to dismiss this as for being for lazy programmers is a serious misread of what is happening.

Just like Windows is becoming rapidly a service model and not a product anymore. So to the IDE and programming environment or editors is also becoming a service model and moving away from the product model.

The good old days of being free to own your software and tools is coming to an end and the servicization of the computing world will continue for quite a while as its a more profitable business model. There will only be niche tools and a niche audience remaining on the old models more than likely.
