If the choice is between sharing my data with a three letter agency thousands of kilometres away and sharing my data with a three letter agency and my employer, you're damn right I'm choosing the former. I even refused an otherwise sensible request from my former employer to install WhatsApp on my phone because I was not interested in using it personally, and they were not interested in providing me a work phone for it.
