The two main reasons why I am currently looking to replace EV with another solution are:
1. Their refusal to take on this very popular and very longstanding sub-stacks request—or at least admit that they can't do so (if that's the case) rather than try to pretend it isn't a desirable feature.
2. Their automatic, irreversible and non-refundable subscription renewals, which may be legal but which nevertheless create a sketchy and exploitative vibe. It's not that I would have said "no" so far if they'd asked me to renew—it's just that I would have liked to have been asked.
