I despise the fact that they keep people from migrating away. They're not giving any option of forwarding the emails for free, which means you can't make a smooth transition out.
Your belief that email forwarding ought to be free, on a platform that does not sell user data, seems unrealistic to me.
Protonmail doesn’t stop you from migrating, they’re stopping you from *indefinitely using their domain and servers, for free*. GMail has an incentive-they’ll scan your emails for information about you and use it to target you on their other platforms. Proton has no such incentive, and no obligation as far as I can see.
They also make it really hard to sell a house, when you sell and move to a new house they dont let you continue to live in the old one for a few months to make the transition smoother.
You have time between the offer acceptance and the closing to move out. You usually can buy a new house on the contingency that your current house will be sold. And you can of course get your mail forwarded for quite a while by the postal service with a simple form.
Nahh I still want to be able to live there, I particularly liked the upstairs toilet, its where I did my best work.
It should be no problems for the new owners to let me in and use it whenever I want. I know I dont own it anymore, but really it would just be unreasonable to not let me use it.
