I'd rather be able to blame myself for my stupid mistakes - not be beholden to Amazon's (or whoever's) MDM profile. Especially when companies don't make it clear that "if you log into your email on your phone using this app, we install MDM, root certificates, have the ability to remote wipe, etc. etc. etc."
I saw that warning when I started to set up my phone and I immediately stopped. If anyone needs to contact me about something urgent they can do it using the work approved IM client that doesn’t require a profile to be installed.
If it does get to the point where I need to have access to my company email, I will have a separate device.
That being said, if my phone was erased, it would only be a slight inconvenience, I can restore from backup.
For me, it's a minor inconvenience at best, not a death sentence.
