I'm not sure if this is the best place to ask this question, so sorry if it isn't. I've been using Articulate for a while to produce elearning materials for students at a university. After years of working solo, I'm beginning to get other people interested in producing such materials. Inevitably, the question of being locked into proprietary software has come up: if we decide to use software like Articulate, are we becoming too tied to something which may become obsolete (not necessarily likely) or which the university may stop supporting (a much more likely scenario). When using software, I usually make a conscious decision not to lock myself into a format which is proprietary or which doesn't have allow content to be exported to other non-proprietary formats. So I guess I'm asking whether other people have been asked this question when deciding to use Articulate and how they answered it.
(I'm not talking about exporting to Word, and I'm not aware of any elearning software that has the kind of migration I'm talking about, so this isn't a critique of Articulate).
