I am with you as a long time user, I would have stayed but I don't need all the fancy features (and AI ?!?) that power users would take advantage of, I even sent a plea asking for a FREE+ with the same limits but just remove the nags for a few dollars a month.
I keep seeing posts with "if you don't want to pay then don't use the service as it costs them to run it" but if you look at the other way round, if I pay for the first personal level but continue to use two devices and limited storage and uploads I am subsiding the rest that ARE taking advantage of the features of that level.
Anyway, as it happens after struggling to export all (700) of my notes to move to Joplin which kept inexplicably failing randomly at different counts, a 50% offer popped up. Starting to worry I would lose older historic posts I folded and paid for a year and magically the exports worked flawlessly.
Despite having now paid I'm intending to stick with Joplin. So far the only feature I'm missing is the favourites section as I had a dozen or so regularly used notes but I'll work round that with tags.
It will be interesting to see where this ends up.
