I am inclided to agree with you that Andy Yen is just an idiot and that Proton is doing it’s best to stay natural and make the most of the situation. However their communications team is pretty lackluster.
On another note, the article I linked is an opinion, so while it is laid out pretty well it is probably not telling the entire story. I have a custom domain on my Proton account so I can Switch if it ever goes to hell. I would advice you to do the same.
Well fair, I just found the Medium article to be more complete than most info that is shared around, but I already assumed that it was not complete. At the end the day I personally don’t have issues with Proton currently and they are still the best thing I can use since it’s located in a country like Switzerland. But I advice everybody to use their own custom domain so they can move whenever needed.
