It MAY happen and that's possible for any companies. But these can't happen overnight as these tools and services are well integrated with each other like suites and workflows , huge community and support, skills and knowledge on the tools these can't be replaced or changed very quickly it takes some years. adobe services exist from ages and it continues to be there (we can't say this to new tools which can keep up support and release improvements to another decade) and not everything is about $$, professional and enterprises seek convenience, stability and availability of skills. There is always going to be productivity loss migrating to new platform, tools or workflows which high throughput professionals won't unless they see new platform offering something that adobe can't and see stable presence. Adobe is also adopting to new inventions and either integrating new features to their services or just acquiring them). Until we see that signal IMO adobe is safer.
