I don't think is worth to pay for a course or specialization beyond the motivation of not losing the money invested because there is no difference at all between the free and paid version, which is more frustrating are the support forums, they are run very cheaply, getting an answer could take weeks and it's just the blind leading the blind, also there is no guarantee that a course offered today will be offered in the future, have that in mind if you start an specialization, if you miss a course it's impossible to get something that you paid for.

The forums and peer-to-peer interactions more broadly are unfortunately one aspect of MOOCs that scale poorly. MOOCs haven't really lived up to their hype (they're valuable but not transformative) because the thing they do really well--broadcast lectures--was largely a solved problem. While the thing that they do poorly--individual or small group interactions--is the part of education that's difficult and expensive. For certain types of content, which happen to line up well with programming topics, autograding systems are another good innovation. But otherwise peer-grading and multiple choice tests are pretty weak.
