I agree. For me, one of the defining features of Sublime Text is that it is a no-brainer purchase. It is inexpensive and a one-time purchase, not an ongoing expense. 30$ per month does not fall in the same category for me.
I am sure there are some pro tools for email using emacs/vim setup.
Actual luxury doesn’t constantly try to upsell you or get in your way in the name of boosting “engagement” or some similarly-disgusting metric.
I want one of those big master lists made for things you can actually own and not rent - from free or non-subscription software to devices that won't randomly brick themselves if a company's server goes down.
I like your idealistic view of what luxury should be. But its not like that unfortunately.
If they did email, I'm 100% buying it the day of its release. Even before, if possible.
