Google says it will pull its YouTube video service from Amazon’s Fire TV and Echo Show devices in a nasty fight between the big boys of consumer tech that leaves consumers in the crossfire. The decision to block YouTube is in retaliation for Amazon’s refusal to sell some Google products that compete with Amazon gadgets. That includes Google’s Chromecast streaming device, an alternative to Fire TV, and an internet-connected speaker called Home, which is trying to catch up to Amazon’s market-leading Echo. Amazon’s high-end Echo Show has a screen that can display video. The power being thrown around by these two giants is the type of conduct that has some talking about the need to break them up by way of anti-trust action.
