That's easy. I need something that works, and there is no alternative. Also, I need something that works the same, or at least reasonably comparably as for 90% of everybody else. Which means I need to use Windows. Not Mac, not anything else.
Sorry mate, but I don't quite get it. On daily basis I use Windows, Visual Studio, SQL Server, Office and maybe few others made by Microsoft. Their software let me have my job and have fun on xbox after work. How can I not trust a company that has the greatest influence on my income and my life?
Software we write also uses telemetry. Much to the point that logs from one day can easily have few gigs. And we do what we can to remove any personal information from them while leaving identification markers used to pinpoint bugs. Do you think it is bad we collect all of this? Hell, this is user's behaviour that we can use to... what? I don't know :)
What makes you think Microsoft does it differently? What makes you think they would cut the branch we all sit on?
Look at VW - one fail and their sales are slapping on face as everyone now would think twice before buying any of their cars. Yes, Microsoft's EULA lets them collect everything they want and it is probably much broader than what they are actually collect. Just because if they see need of one more counter they didn't think about they can just add it.
If I doubt in intentions of any vendor (be it software, hardware, food, water, whatever) I just don't use it. Simple as it. That is why I don't use facebook for example. If I will ever doubt in intentions of Microsoft, especially when my job relies on their work, I would stop using their software. There are many other occupations that don't require computer at all.
