It's shorthand for stating a dislike of Google's reputation for short term thinking around products - whenever there's a new Google launch many people's immediate reaction will be "Looks ace, but is it worthwhile investing the time and energy necessary?". That's a complaint Google should take seriously. It's how lots of people in the tech community view Google. As you say, it seems to be posted every time Google launch something.
There was a great comment by jsafi here on HN a while ago suggesting why Google are like this - https://news.ycombinator.com/item?id=19553840
It's hard to imagine a way they could change it besides stopping launching anything that doesn't have a long term plan in the company.
