The FaceTime software, would have done plentiful towards the industry & others, if it became open sourced.
But nope, they decided to make it exclusive for only within the Apple product bubble. Now we are supporting with so many video apl software/ tools. It's just fragmented. It's okey with competition but this is far too much. Also the quality, safety have lessoned.
Don't purchase & start using it from the first place. Save yourself plenty of resources. Focus on something else productive & valuable.
