I find subscribing to medium worthwhile if only because it gives me the equivalent of a subscription to those major (also-paywalled) news outlets. A subscription to each of them (or even, in some cases, only one) would be more expensive.
That said, paywalled posts aren’t generally of a higher quality than non-paywalled posts. The only real benefit of the paywalled posts is that, by TOS, they aren’t allowed to be about how to maximize your medium followers or shit like that (or, for that matter, to contain any ads).
