It is a burden however, and one that isn't necessary if your company has a sane BYOD policy that protects them while not being too invasive.
The reality is, convenience wins again here. I, for one, don't give a shit what control my company has over my phone. Not only has nothing ever happened as a result of me using a BYOD policy, the overall rate in the industry seems acceptably low too.
I only have 24 hours in my day, I can't be worrying about things that aren't likely to effect me in any material way. I simply don't have time.
