Adobe won’t be hurt by this in the professional market because they have inter-app compatibility and a somewhat consistent language, plus you need their software to work with legacy files. Adobe is cheap, you can get the full suite for a very reasonable price. Competing software is always niche and you need to learn each one individually as they don’t share UX principles nor ontologies. They might be free now, but imagine managing individual subscriptions for each one later on; a nightmare for individuals and companies alike. Just needing to sign-up for multiple apps individually is a headache, all the emails and updates, etc. Unless someone makes a comparable and comprehensive suite, they won’t be actually competing with Adobe.
