Most likely because the Linux path they all went did in the end not really solve their problems (most trading related apps, Excel APIs, Reuters Eikon, BBG, ..., still prefer to run on Windows platforms). But maybe also because Windows 10 in the end did not turn out so bad as many feared...Linux has its place but it is definitely not the platform of choice for most traders (else why does nobody at front offices trade off a linux machine...). But hey, I do not want to start an OS war (which can never be settled). Use whatever suits you best, for me Windows 10 does a pretty decent job and I like it. I just shared my experience.
Well, I would think that they still haven't gone to w10...I haven't. So what you suggest above likely doesn't apply.
There were folks that alleged (previously) the same things Snowden and wikileaks later revealed as true; but they (folks) weren't taken seriously by the masses.
For me, I express my concerns to others. They can inquire further, or do their own due diligence, or do nothing. But I don't need for others to agree with my opinions. If they like win10; I love that fact.
My point is: I wouldn't conclude that silence equates to acquiescence.
