Hawkinson's timing was good. Although home automation has been around for decades, it's still far from mainstream. At the same time that SmartThings launched, Nest Labs, a "smart thermostat" created by former Apple engineers Tony Fadell and Matt Rogers, was hitting the market.

In January, Google bought Nest for $3.2 billion, demonstrating that the tech giant was keen on colonizing smart homes, much like how it colonized smartphones with the much-cheaper Android acquisition in 2005. In its World Wide Developer's Conference in June, Apple showed off its HomeKit concept, which envisioned a Siri-controlled home — and the race was on.

The intentions for this experiment are probably to help increase engagement. One could even argue that for content Twitter deems to be "breaking news," putting important tweets from the accounts a person's Twitter friends follow into that person's main timeline could be valuable.

The developers for BombGaza and Gaza Assault: Code Red could not immediately be reached for comment. Other games that simulate Israel's Iron Dome and Hamas rockets remain in the Play Store. Have something to add to this story? Share it in the comments.
