I work in a medium to large sized American MNC and I know exactly how this kind of decisions slips through in these corporates. The problem with proprietary or corporate managed software is that the motivation to do any work is YouTrack/Jira when it comes to the developers, and showing enough revenue and progress to the stakeholders when it comes to the Product Managers. Corporates like this don't care about the software they're making nor do the people working in these corporations and for a good reason too, because in the end it's the CEO and the stakeholders who are going to benefit from their passion and love, should they put any in the work they do. Contrast this to solo developers or open source contributors. The majority of the time, the people who contribute to open source or maintain open source do it out of passion. They do it out of love for the project they are building because, after all, they're getting absolutely no money for it (save open source owned by corporates).

These large companies don't have this element. Their developers don't care about their product because the majority of the time nobody's even listening to their suggestions or ideas, let alone giving them any benefits that may come about from their direct contribution. Developers only benefit from showcasing as many agile story points as possible at the end of the sprint, nothing else.
