Said it above; but I 100% agree with you. My point has "second-order" effects.
I'm not necessarily saying your email has to go away and you HAVE to use hostdime. I'm saying the goal of McDonalds is to dominate and obsucre everything and anything that cuts into that is useful, especially third-parties like Hostdime. For someone like me that finds it too hard, but also finds gmail unacceptable this is a good (and should be obvious) solution.
How I explain this in real life:
"You'd be stupid to run a business off of gmail. When your phone or internet or electricity goes down, you can call a human and yell at them because you pay them. What happens for google? This is why I pay someone."
