I dont blame em for going with that decision. Maintainer/devs are also wearing customer service/ PR and bookeeping hat on top of the things they build. Things cost money, especially time, call it greedy or not but people have to pay housing and food. Its tough and similar to a lot of industries, nobody cares until something goes wrong. All the best to this person 👍
I would have suggested silent.link , while you can get a number not tied to your identity via esim, the main focus of numbers is a receiver for text and calls(also because it avoid people creating spam phone calls/txt). Which was originally for 2fa that only had cell # as an option. Also a number requires the user to be vigilant in paying their annual for it or they can lose the number. Also I think they can only cater for users in US, Canada and maybe UK.
