what's the point of GitLab or Mattermost being open source when they clearly want to control/restrict/monopolize use of their applications?

- We can fork it if we really don't like that direction, but think what's there is valuable.

- We can propose Merge Requests (as they are on GitLab) that might be higher priority for us personally than for the company, which might accept them just not have the resources to work on them itself as quickly as we'd like.
